Hot Rod Deluxe HELP!

[soberskipper]

Hey y'all,

I've been trying to bug people at AX84 for some help on this and I'm running out of time... and HAIR!

Hot Rod Deluxe
symptoms: sounds like "ring modulator" all the time no matter what. Buzzy, harsh, and awful. Yet you can hear the regular signal underneath the noise.
Will not bias past 3.3ma but Va is fine.

I have tried all non invasive measures including tube changes, speaker, etc. Makes the same sound when I plug directly into the "power amp in" of the loop, thus convincing me that the problem lie either in the bias supply or the output section.

All components in bias supply measure normal, all components in output section measure normal. I have desoldered the OT and checked it for continuity.... everything checks out fine. I even replaced a filter cap because there was some yellowbrown goop coming out of the + side...

Except no matter what I do, check, or replace... I can't get the bias pot to give me more than 3ma of current to the tubes.

V3

pin 1 - 208 V
pin 2 - 17.3 V
pin 3 - 26.3 V
pin 6 - 205 V
pin 7 - 18.1 V
pin 8 - 26.5 V

V5

pin 3 - 342 V
pin 4 - 341 V
pin 5 - (-44V)
pin 8 - 9 mV


Any thoughts?
Let me know if I should post a schem, gotta run right now though..
thanks
