Studer A807....testing the PSU!!

[Misterevster]

I'm aware...from other searches...that the A807 PSU has 'test points'...and believe I need to check correct functioning of the unit.

I've a 588 page on-screen service manual....am at the PSU section (page 314+)...and I'm driving myself crackers trying to spot these points.
Can you...or someone out there...please help me find 'em??

Possibly in front of my eyes right now....and I'm failing to see!!

The Test Points are shown on the circuit diagramme;
Tp1 = 48volts. Tp2 5v6 etc.

I have it as a hard copy but believe it is available on HiFi Engine. Here is what could be an e copy.

This one is a '91 Mk2....does it differ significantly from a Mk1...??

Very similar. This may help, from memory, over 30 years ago, I think this has the modifications.
I don't have anything else left on this one.
