Hi
I have one of these crappy ANT modules that i would like to use.
I have the manual and checked all the voltage testing points and seems to be ok...but i cant get any sound out of it.
I used 1k resistors at pin 1 and 2 as input.
The unit is recapped. It was strange that i found a c1 220mf/10v in a place were i was reading 22v?
I would like to change opamps also...is Ne5534 a good replacement for the UA741?
What about the second opamp next to the trans.?
Any other suggestions to improve it?
