Perhaps someone would be able to enlighten me. Hopefully I just finished repairing an SHP-1 amplifier with an early verion Driver Board (319295-A) which had the common problems on the right Channel (burnt R75 and R76...fried Q16..and damaged Q17 and Q18) I recapped it, checked for off value resistors changed all Q12, 13, 14, 22, 23, 24, All four output transistors, cr51109 and cr51110 Also Q11 (under heat-sink)etc etc. Checked the Bias pots both at just under 3K and responsive...which I brought to the minimum resistance and connected the speakers. Connected it through the jig with a 75w bulb and it has been cooking for over an hour..all is cool on both channels except for q14 and Q24 at 102F.. compared to the rest of the components at 83-84F
Here are my questions:
After all was done,
1-) Test (g) and (h) for the Left channel (Which wasn't the fried channel) gives me 97-99 ohms according to Tony Miller's SHP Amp book (which I understand to be tested at the Collector of Q16 and Q26 instead of Emitter as printed in the book) RIGHT CHANNEL tests under .5 ohm as per test (e) and (f) at collector of Q15 and Q25 What am I missing?
2-) The Schematic shows C49 and C64 as .022uF....the unit had .047uf/100v when I got it... and the parts list on the schematic shows 1uF tantalum at 35v...Which one is correct?
