After months of trying unsuccessfully to get a valve tester, I was lucky to find a very nice example of a Paton Palec VCT.
Although it is only an emissions tester, I have heard only good things about this particular unit. While I wait for it to arrive, I decided that I would replace the caps. However, I am having trouble reading cap values/voltages from the schematic as it is quite low res. I was wondering if anyone could please send me another copy of the schematic.
Thanks

There are a couple of variants of that and not a lot of caps. Resistors also fail.

Mine is a VCT-V, which as a 1V not a 6X5 (as 1/2 Wave) and the 6V vibrator PSU.

I have a couple of variants of the manual, which was / is actually on the Net.

Beware of the meter movement, of which there is more than one type. The one in mine has screws behind the metal bracket holding it in. The unit has had a very mobile life and one vibrated loose to the point that it caused a flash over & meter repair. Modifications have been made and that will not re-occur.

For some reason they used the 1V and Vibrator with a UX-4 socket such that they could both fall out in transit and be interchanged to cause havok. The latter type had a different & much tidier chassis, but in keeping with bad habit's there are two paper caps in a bad spot and they will be cactus.

Thanks for the pics. Very nice units you have. Very neat layout on the inside. Quite well designed in that aspect. If it's not too much trouble, could you email me a higher res copy of the schematic for the VCT. The one I've been working off was for the VCT-V but I don't expect there to be any changes to the circuitry over the other side of the transformer.

Hmm, I see your VCT has a green band. Mine does not. Does this signify anything or is it just cosmetic?
