Hi,
I’m trying something with little succes…
Is it possible to cable the input signal parallel and create 2 amplifiers with one input signal? (I ise 2 k4001)
When i try to do it, i get nothing but both amplifiers work when directly connected to input.
Thanx in advance.
That should not be a problem.
Most likely, there is a wiring problem.
Thx for your reply 
I accidently used one time ac to power the amplifier (in the beginning) could that be the problem?
I will get a new k4001 and try it again
Thx!
That is definately not a good idea to use AC as apower supply.
