Hi Michel,
If possible could you send me the circuit diagram of the A28II.
<agxaudio(at)hotmail.com>
Last year I asked for some advice about a cracking volume potentiometer the advice to clean it solved the problem, unfortunately the unit has suddenly stopped powering on and all the internal fuses seem fine so maybe with the circuit diagram I can find the fault.
Many thanks
Ant G

HI fellow Sugden listeners

I would be very pleased if someone could send me scematics for Sugden P28 and A28II?
please send to "lasse at nylanders.dk"
I've bought a secondhand P28 in order to have a bridge setup with my A28II, but the P28 sounds terrible, and the PCB shows signs of burned resistors. All power Transistors have been changed an non of the are the same.

Is it even possible to have the amp restore so i can use it with mu A28?

If not I will try to use it in bi-amp instead any one has experience with this combo?

Hope someone can help me out here!

Thanks

Hi Phil
I saw your post to Lany and I was hopping you could help me out a with schematic diagram for the A28II if you have it.
A while ago it stopped working and I have put off investigating further apart for a quick visual inspection until I have more information.
It would be most appreciated if you could assist.

Thanks

Hi Michel

Saturday morning my A28 gives a big constant noise to speakers.
A strong DC signal was added to played music.
I immediatly stopped the buzz by switching off the amp.
Your opinion ?

Regards

Phil

PS : I'll post pics today
