Another chanel is up and running!!! Must be something with connections, wires or something alike on the first one. I'll check the cap.

I'll take on the buzzing channel tomorrow. Can't express enough gratitude for both of you Buzz and Sonny.

Did you have any other trouble firing up the channel with the buzz? Does your second channel work properly? Think about it with a glass of wine. Step away and retsckle tomorrow.

Second channel - impeccable. I'm sure channel one buzz has something to do with connections. Gotta recheck that tomorrow. It's getting late here.

Maybee i have been unclear or i have forgot to mention .. Those caps has to be 100pF with ezw20n/p20-z. The 47pf is for ezx10n/p20.

Some troubles have their bright side. I'm glad you've spotted it. 100pF for C12 & C13?

Ahhhh - this is news to me also Sonny.

My amps have not been oscillating but would you expect this to impact on the sound quality ?

Tomas: Yes that is correct C12 and C13.

Mike: The problem is, if you have cable that is not screened correctly, you could pickup HF on the signal cables as the amp has a bandwidth of more than 2MHz. So by making the capacitors 100pF for for EZX10 and 220pF for EZW20 will reduce the bandwidth to 50% making less sensitive to HF injection on the signal cable.

Currently building regulated supplies. When finished will compare yours & my amps again and check out this bandwidth thing.

But my instinct is to keep widest possible bandwidth and filter ( and possibly buffer ) the incoming signal if necessary.

Will report when I make tests
