JMF Spectra 30-T Bias issues

[Mark Black]

FWIW the 120T schematic specifies +/- 18V using the same 1K & 820R current limiting resistors.

Edit: The 120T schematic also specifies 4746 (presumably 1N4746) 18V zeners.

Thanks to everyone for all your help. Mark, I'll lift one of the diodes and see if it's the same as the ones in the 120t. That's a big help if it is. Thanks again!
