So ...... Time to bite the bullet and get on with the monitor. Never had a colour vector monitor before, let alone worked on one.
Here she is. Notoriously unreliable WG6100. Looks pretty good from this side:

No burn. At all. Which is where the good news ends, and the bad news starts. As a quick glance round the other side reveals a few missing components:

Needs:
HV board.
Deflection board.
The 6 frame mounted transistors.
Neck card.
Missing wiring to be re-instated.
And a full rebuild and upgrade to make bullet proof.
A loose HV cage and board were supplied with the monitor. Here's a list of all parts replaced and upgrades applied to the HV board, and what it looked like when I'd finished:


Next up, deflection PCB. I struggled to get hold of one of these. Really struggled. Finally tracked one down to a guy in the US. But he refused to ship to UK. Grrr. So I asked him to ship to my cousin who has been living in the States for past 20 years. No problem. When I sent the seller my cousin's address, turns out that they live only 3 miles apart. He dropped it round on his way home from work .... Small world.
Anyway. First thing, remove LV section and fit LV2000.

After:

In addition, the following parts were replaced / upgraded:

Next up, frame mounted transistors x 6 and re-instate wiring:

Time to put it all together:

Starting to look a lot better .... So time to test ....
Everything laid out on the bench (utility work top ....):

Switch it on ..... and bingo:


Needs picture size and focus adjustments. But that'll wait until later in the week. Hopefully now just a case of transferring it all into the cab and job done.
