The Eagle has landed ! (aka the Lunar Lander project)

I like it

I suddenly realized we have a A0 printer at work ! Bad thing is I don't come there very often....

Sent an e-mail to a colleague if he can print it 1:1 so we don't have to do the "stitching" (the printer didn't do the edges correctly on yours' Etienne, I had to "guestimate" the distances...no biggy for this first test...)

Never sure when I will be at the office (almost never). Maybe he can sent it...

Then I guess all I need is some black cardboard and do the creative work

Thanks Jörg ! Don't you think the 6 mm. will become too thick ?

Jochen

No, 6mm is taken from the original bezel glass.

[level42]

Da..... Keep mixing up your first names !!! Sorry !!!

Really, thought the originals were much thinner....O well as long as it'll fit

Yesssssssss, found a second TV with a 48cm. tube here in Holland. it has exactly the same tube (A50-120W) as the TV that Ully picked up for me so if this works I know the other will too

There were pictures of it playing so it is good and no burn in. Hope the corners are still sharp. This TV is from 1968 so only one year younger than I am !!!! Again, a bit sad to hack it up...but a man's gotta do what a man's gotta do.

Guys do you remember the screwed up picture I had with the original G05-801 ? The BW FAQ says that this can have two causes:
1) bad setting of the linearity pots
2) bad yoke

Let's hope it is nr. 1) !! I got a pot kit for it from Bob Roberts so hopefully I will be able to fix it if it isn't just setting the pots correctly.

Just picked the TV up:

It works great still...and no cap-kit done
only problem is mechanical with the channel selector but that's not really important for me...

I`ve modded with PRC some TV for the uni cab hellomaten. Had the problem, that the TVs must be switched on mechnically.

we solved this issue by adding a simple wire bridge for the switcher on the chassis.

I love it ! , good old Philips !

Nice hack. However not all TVs need that. Some come up in stand-by, some simply power up and in some you can actually program what they do when "power returns". However, we are talking about a 1968 TV here.....If I needed it that way I could simply let it on with the mechanical switch.

However, as you probably know, a TV is a raster device so it's completely useless for a vector game. The ONLY usable part for a vector monitor is the tube and that was what it's all about...

[level42]

P.S. The first one to say "but you need a vector tube" will have to buy the first round at Eurocade !

[level42]

OK....a mini road-trip report for just another arcade part.....

For a long time (and I mean pretty long) I have been looking at marktplaats to find a 19" BW TV. I want them to BUTCHER THEM ....ahum sorry...I want them to give them a glorious new life in one of my beloved arcade cabinets.

At one point in time I desperately searched German E-bay and actually found one. With the help of SuperUlly (who hopefully is still alive and well.....) I could buy this little gem and it's waiting now for transport to the low-countries.

However, mean-while more BW monitors and cabs were added and all have at least some burn in some way. The best one I've got is the one in my Asterock which only has a small dot in the center. Some people say that a real vector monitor should have that dot but....well. Indeed I can really live with that one. However the other two clearly show burned in attract mode screens and well.....I just don't like that.

Of course buying a brand new fresh NOS NIB tube is still possible (and hopefully will still happen with the help of HI) but the costs are pretty high. I could buy them now for 149 USD but then comes the shipping and on top of that import duties taxes (also over the shipping costs !!).

So...of course I kept my eyes open at Marktplaats. However ALL the TV's I saw were either the really small portable one's OR they were WAY too large. There were also 50's TV (too old). End of last week I finally hit the jack-pot with that nice Philips TV mentioned above. Gave the seller a call, agreed on a nice price for both and picked it up:

My new car has built in navigation.....for all Western Europe.....

The place where I need to go is called "Boven-Leeuwen" (Upper-Lions haha, yes there is also a "lower-Lions")....this means I have to take only one high-way the A15. At some point I have to cross a bridge that used to be a toll bridge in the past. I rarely cross it...so here's a pic:

As you can see we have a great summer this year !  

Getting close to the seller's place.
You know that the vast majority of Dutchies live below sea level and we made some dikes to protect us from the water...

photo by Level_42, on Flickr

In 1995 however, people still had to evacuate this area because the dikes were threatening to break under the pressure of extreme loads of melting water from the Alps.....(and some neglected maintenance)

photo by Level_42, on Flickr

Luckily it didn't happen.....and this beautiful area was spared...

I arrive at a nice home....the seller is an older man of in his 70s. He's a hobbyist for sure. He shows me has garage where he has a workplace and lots of old AV equipment like the first Philips VCR's (no, not Video2000), radio's, TVs etc. Some nice radio's from 1928 !

We have some nice chat and at one point he asks if I will be using the TV to decorate my room or something......so I stutter a bit and say yeah....yeahhh.....it's really something I've been looking for for some time....(come-on I couldn't say what that I was going to BUTCHER IT !!!.....couldn't break that man's heart

So, put it on the backseat of my car, tube face down of course, nice blanket under it, safety belt around it and off we go.

On the road back we have even more nice Dutch summer weather:

photo by Level_42, on Flickr

This isn't just rain, it's what we call a "cloud-break". I have to reduce speed to about 80 to keep things safe.....luckily I'm almost home...

So I quickly unload it and of course first I have to test it (no signal needed):

photo by Level_42, on Flickr

This is how it looks turned off:

photo by Level_42, on Flickr

I like it....I can't help it....it's only 1 year younger than I am !!! .....but a man's gotta do.....
It opens up really easy.

photo by Level_42, on Flickr

In those days, things were built to be serviced.... there are four very easy "plugs" to pull. If pull only the top two I can work on the PCB without having it loose completely.....ahhhh....those times....

photo by Level_42, on Flickr

TUBES TUBES TUBES !!!

photo by Level_42, on Flickr

Remove the lower two plugs and there is the entire PCB.

photo by Level_42, on Flickr

Hello sweety....it's you I need !

photo by Level_42, on Flickr

Raster yoke....took only one screw to unscrew to remove it. One thing worries me a bit, those "wings" at the side of the neck look like magnets to "converge" the picture.....let's hope I don't need that anymore.....


photo by Level_42, on Flickr

OK listen....this is only gonna hurt for a very short while.......there.......already done !

photo by Level_42, on Flickr

(Yes, we are re-doing our walls....)

Ahhhh.....Nice Philips tubes MADE IN HOLLAND....and still working.....no cap-kit installed !!!

photo by Level_42, on Flickr

I think I'll get the tubes out and put them on marktplaats.....hey maybe it helps a TV collector !

"ooo hunny.........there's something great on TV tonight ! Come and watch !!!"

photo by Level_42, on Flickr

Our "victim". She looks a bit brown and dusty, but not too bad at all....

photo by Level_42, on Flickr

Mmm, I guess that brown stuff is nicotine set-off on the tube. Or maybe just "heat" from the TV itself ? It doesn't smell like smoke at all though (neither does the rest of the TV)

photo by Level_42, on Flickr

With some gentle and careful scrubbing with a "schuursponsje"....

photo by Level_42, on Flickr

Yeahhhh, much better......we must be nuts to do these things, no-one will ever see it when it's inside the cab....

The tube number...shame the brand is torn. It looks like this wan't a Philips tube. The data sheet I found was from Telefunken but that logo is not Telefunken's....

photo by Level_42, on Flickr

Completely clean and good to go another 30 years and ready for the transplant !
(If it works !!)
I measured the distances between the corner holes and they match the original perfectly

The tube number...shame the brand is torn. It looks like this wan't a Philips tube. The data sheet I found was from Telefunken but that logo is not Telefunken's....

photo by Level_42, on Flickr

I mean it´s "VALVO" logo:

[level42]

Nice one,thanks !!! Remember it from some very old radio tubes....there was another logo on those tubes too....which was not so nice ......

Very old brand....owned by Philips for a very long time.....not much left of it now......nice history here:http://de.wikipedia.org/wiki/Valvo

Anyway......as always the proof is in the pudding....

However, before any surgery is done, the doctors have to know if the condition of the patient is good enough for the operation so....

photo by Level_42, on Flickr

I love my Muter more and more. I hooked it up to the tube that belongs to the g05-801 that came with the LL and it showed some pretty poor performance. After a short "cleaning" with the Muter the gun showd excellent condition again.

However, this tube teste out just fine right away:

photo by Level_42, on Flickr

OK, so out comes the (temporary) G05-802. Let's remember why I want to do this:

photo by Level_42, on Flickr

Ready to go.....I removed the original dag wiring, gonna need it for the -801 as that one is badly corroded.


photo by Level_42, on Flickr

Removed the yoke from the 19VARP4 tube. One screw on the neck clamp and two hot glue pieces which came off very easy. Installed it on the "new" tube. Amazingly (or not) the glue points still fitted PERFECTLY to the new tube....of course not sticking though....
By far the scariest part of the whole operation is tightening the neck-clamp again ! We all know the neck of the tube is by far the weakest part and......how tight should it be ?? Wel I just guesstimated it....surely not too tight....but also not too loose....

It is also important to get the yoke exactly as straight as it was because else the picture will be not perfectly horizontal on  the screen.

Mounted frame back on the tube and presto.....I do notice that the color of the screen is a bit darker on this tube...

photo by Level_42, on Flickr

HV cup, yoke wiring and neck connector reconnected....

photo by Level_42, on Flickr

And the it was power up !!!

Again, camera doesn't pic up the whole picture at once.....

Also: this was in full sunlight (yes, it was actually sunny for a while this afternoon).

Since the monitor was now out of the cab anyway I could set up the pots as best as possible. Turns out It will be best to replace the monitors brightness and contrast pots and all the position and size pots on the game PCB too....they were a little jittery.

But it works, and I'm really happy !!! It is REALLY a piece of cake. The hardest part is finding a TV with the correct tube size and the tightening of the neck clamp.

Does anybody want a used and slightly burnt 19" B/W tube ??

[Etienne MacGyver]

WHOOHOOOO    operation Succesfull ! 

now that the joke is in the correct position, maybe secure it a bit more with some hot glue ?

[level42]

Yup.......found the gun but where are the sticks when you need them......
