Question: HR-10B Power Transformer

[Mike Hardie]

Help!  I'm working on a dead HR-10B and have found the B+ to be well above
specs. (Cofirmed with two different voltmeters.)  According to the
schematic the transformer should be putting out 410 vac but its actually
around 450, just at my "personal limit" of +/- 10%.  Downstream of the 6X4
rectifier things get worse likely because of the RMS to d.c. multiplying of
1.4.  All the other B+ related voltages are also high.  The transformer
doesn't seem to run hot but the 1500 ohm 10w resistor in the power supply
sure does.  Anyone else had this problem?
