Help with a Sencore TVA92

[aquaman8]

Hi Brian,

Thanks for the response. I will have to look for a schematic for the VA62 to check out the meter section. Any ideas where I might find one?

Hopefully there will be some similarities between them, but the VTA91 is an electro-mechanical nightmare with a lot of microcontroller controlled relays switching sources and attenuation, and relays always make me worry! There are also many opto-isolators used to keep high voltages away from sensitive digital lines! Quite a troubleshooting adventure! I'll keep everyone in the group informed as to how things go!

I will also check out the diodes, thanks for the tip!


Any ideas if there is a Sencore repair group/forum around on the web? Hopefully this will be a common fault and someone can point me in the right direction! I' hoping!!

Thanks again for your response,

Mitch
