I recently acquired a Dynaco Stereo 70 Series II with one of the cathode resistors blown to smithereens - haven't done any further testing yet.
Questions for the Dynaco veterans -
1 - Where can I get the parts, schematic, etc. to perform the screen resistor modification - and replacement cathode resistors?
2 - Is it safe to assume that if the cathode resistor is blown, the finals also need to be replaced on that channel?
3 - Why in the hell did I ever sell those Dynaco A25 speakers I had in the 70's?
Thanks in advance
