Can you use another descriptor, so that we can see what your opinion is?Bonsai said:Sugdens are really crap amps.
I suspect an adjustment to be needed on those 1k pot, because one side of the amplifier run hotter then the other. And there is a ceramic resistor close to the pot is running very hot, over 200 celsius unlike the other side wich is running at 170.
If i can find the value they should be set so i can see if they need to be adjusted or not would be great.
Thanks again

Perhaps it sets the quiescent current. Or perhaps not. It all depends on how experienced you are. The hotter one could be the correct one. They do run very very hot.
It's up to you !!! Would you know how to measure the quiescent current, or the output DC offset voltage so you could readjust it back again.
Just don't want you to damage it that's all. It may all be normal and within spec anyway.

Hi Bonsai,
Could you be more specific please Sugdens are really Cool ? maybe.
Mooly said:Dobs,
Whats the value of this ceramic resistor and what is the voltage across it compared to the other channel. Lets try and put some numbers in.
1ohm 5% and 48v ac pass across both
Mooly said:JES = J.E.Sugden Any more thoughts on what to do ?
How experienced are you with electronics etc.
You think they will answer that kind of question!?
I think more i will get something like.. Send it to our authorized dealer for a service check-up.
I sent two modification suggestion i made on my A21SE to JES, one minor and one i consider major and i got funny answer... So i dont expect anything positive from them since.
