Help with a Sencore TVA92

[aquaman8]

Good Afternoon Gentlemen,

I am not sure if this piece of equipment is vintage enough to post here, but I am out of sources. If someone could recommend a more suitable site then I would try there! In the interim, here goes!

Bought the unit on eBay...description said problem with B+...so I knew it needed some attention. Turns out that when I got it many things did not work, principally the DVM. When set to BIAS VOLTS, I get some -8.8 to +17 over the range. The output on the jacks is 0 to 30 VDC as it is supposed to be.

Anyone know what common faults with this unit are or where I could go on the Web to find assistance?

Thanks for your time,

Mitch
