The first thing to do is check resistances against the manual.  If that passes go on to the voltage measurements.

Post only those that are +/- 15% out of spec.  Also post the expected measurement.

A quick check on the internet and I couldn't find the manual or test pages.  Our home was wiped out in hurricane sandy with all my paper work thats why the foreplay hasn't been used. Where could I find that page? Thank you again for your help. This was a purely stock build with the gold rya upgrade and recomended dayton output caps. Regards

Just the voltages on the 9 pin sockets will be good enough.  Pins 1, 2, 3, 6, 7, and 8 on each 9 pin socket will give an overall indication of operation.
