[HAM] (UPDATED) OT: Traynor YGM-3 Guitarmate Amp

[Ian Hooper]

 Tube sockets that have arc'd or otherwise been burned are often best
replaced as there is sometimes a 'track' left, which promotes further
arcing.  Blocking cap c27 from the tremolo osc and bias supply  (D1,r44
etc)could also be culprits. Check that the bias at the junction of the two
100k resistors (r21-22) is stable.

Those older Traynor/Yorkville amps are practically indestrucable, and
perfect for hot-rodding.

cheers

I was playing around with it a bit yesterday and the arcing on pin 7 of the
EL84/the blue wire of the transformer occurs when a loud note is sounded. It
seems it can sit happy when there is little or no input signal, but when I
hammer a low note, fireworks.  I guess I'll order some new .1Mf 400V caps
and see if that helps.
