hi guys,
it's going to get me a couple of days to get a hold of a few 5W resistors to play with (220 to 270 Ohm) [always takes time to try to consolidate my MOUSER shopping cart]
in the meantime I think I am going to try to test the amp providing the -50 VDC with an external power source and see how it sounds now that I should be providing something in the vicinity of 400 V (provided I have not blown the 7189A's when when I plugged the amp to measure voltage after installing the bridge rectifier)
I will come back to you with the results
thx,
