Found a weak HV filter cap (old salvage part) have new one on order. Will be intetresting to see if the Zobel is still needed to prevent the motorboat on the Altecs...
Need an audio brainiac...Stumped...
I just scratch built a "dynaclone" ST35 6BQ5 power amp from the schematic and stayed true to the dyna design save i used a 5u4 tube HV rectifier vice the diode dyna design.
The amp sounds fine on 3 different sets of speakers (Infinitys, Magnavox/Jensen alnicos, Realistic Nova 10's) but motorboats/farts when hooked up to my newly aquired Altec alnico Santanas. 2 other tube amps and 2 other solid state amps work fine on the Sanatnas.
This happens only with that one amp and speaker combination (Dynaclone and Altec Santanas)
