.....and thus Polder visited me today with his tube !
Man those 25"es are heavy beasts.
Since my wife and kid are away today I have no problems setting up workshop


Operating the rejuvenator is not really but a bit complicated, at least you closely have to follow each step. Sometimes the manual is not very clear or instead TOO clear maybe...but we manage.
The thing I hadn't done before was setting up the cut-off correctly before measuring my tube.
So, this time I closely followed the manual (hence iPad) step by step.
Although the primary steps made it show somewhat better results, I still wasn't very happy about them:

So I decided to rejuvenate the guns on setting "Clean" (which means the lowest current used, and let's say the "softest" setting.
We saw some nice little fireworks in the neck of the tube (like expected & intended for the Green & Blue tube. The Red one (which was the best to start with) didn't show much fireworks at all.
Regretfully I didn't take a pic after the rejuvenating but the Green & Blue guns had jumped from 0,5 mA to around 1,0 mA !!!!!
The Red gun shows about the same results, so strangely it's now the "weakest" one of the three but still good enough...
Of course we also checked Bart's tube and decided we shouldn't really mess with it. The values were not ideal but definitely in the "good" area.
Of course it was time to check the result:
So we "installed" Bart's game PCB set, an iso-transformer and a switcher for the PCB set and......

We have a very bright and clean picture !!!!!!

(Small dark band in the top is caused by the camera)
It is a difference between night and day seriously !!! Woo-hoo, my first successful rejuvenation. Buying the Muter definitely paid off now, impossible to find a med-res 25" tube today (well almost).
We do still have some minor issues, there's still some flickering but I'm pretty convinced that the bad neck-board pot meters are the cause for this (still waiting for delivery of the new one's). Also it's almost impossible to set-up the colors correctly with these pots as they developed a "sweet spot" where they work worst, but are supposed to be set to....
Also there is some edge converging to do later.
I'll post some video a bit later...
