Triac VDU Driver Board

Hello, all.

I work in a recording studio, and discovered via the magic of the internets that the VDU Driver Board for our SSL recording console is the same as the board in the Triac. Also, the manufacturer of our console no longer supports it. The Denford forums here have been the only place I've found anything remotely helpful.

My problem is this:

I am trying to put together a capacitor kit for our VDU driver board, as we suspect the caps on ours have dried up, or are on their way there. I cannot remove our driver board right now, as this would result in unacceptable down time for our client. I do have a board on loan from a colleague, but I cannot make out the specs on many of the caps, because all the components on the board are very close together, and my colleague would rather I not de-solder his board.

Does anyone have a schematic that would show the capacitance ratings of the capacitors on the board? If you do, that would be incredibly helpful.

I did search the forum, but found little.

Thank you in advance! The board I'm referring to looks like the photo at this link:

I've had a look through the old filing cabinets and couldn't find any information on VDU's.
We may never have had that level of detail anyway - we'd have just replaced broken monitors with new ones.
These posts may help you though:

Thank you very much!

Wound up just swapping monitors out and re-capping the board.

Works like a champ now!
