Yeah, kinda thought that might be the case. Yep, c-8.  Resistors don't use mfds.  Also noticed B+ is about 14 volts low at the rectifier cathode, but plate voltages only about 5 volts low, i.e., 140 reading 135-138.  Possible problem?  Unfortunately don't have any 25z6's to replace it with.  Anyway, will replace c-8 and see what happens.  Thanks, Terry.  Ed

Doubt 5v is going to make much of a difference. If you like excitement you tie a couple of 1N4007 across your 25Z6. Did I say that???  [Image: http://philcoradio.com/phorum/images/smi...on_eek.gif]  That will get ur 140 up the abt 160.
Yeh, probably a good thing I don't have any of those or I might be tempted to try that.
