Installed a Triode USA cap board in my Stereo 70. Referenced to the original schematic, B+ nodes "D" and "C" measure right on the nose. Node "B" (between the 6.8k and 22k resistors) does not measure very close to spec but is still within 10%, which is acceptable per the original Dynaco manual.
However, node A (other side of the 22k resistor) is 14% low, which is definitely out of spec. Any idea why this might be? Anyone else using the Triode cap board notice this? BTW this is not the classic SDS Labs cap board, it is the Triode USA "Upgrade" cap board.
Thanks.
