HH Amplifiers Performer schematic

[Nyqusit5]

Hi all,
I have an old Perfomer on my bench. Does anybody have a schematic for this amp (at least the preamp)? It isn't on the usual websites...

Hi
Havn't seen many - you may like to keep an eye on this site who may
have it eventually.
HH Equipment schematics
They mainly have the power amps.

Think they mean almost free !
They also have some early parts for H&H and Laney.

Thanks but I have already been through these unfortunately. Still looking...

Hello
I search also the scematic of this amp.

Did you find it ?

[Nyqusit5]

No , I repaired the amp without it...

[pio]

Ok,

Perhaps, you can help me.

My problem is the channel 1 doesn't work and the sound of the channel 2 is very bad

I don't know if someone else, before me, modified the wiring inside the amp, or if the problem is electronic.
That's why I search the schematics.

also the LED of channel 1 and 2 are switch on at the same time.I don't know if it's normal

From what you describe, it could be a problem similar to the one I had on the amp. First of all, look at the switching part of the circiot: it is located on the top and lower boards at the opposite end of the controls. There might be some burnt components as the circuit tends to get hot (not a reliable design...)

Then check both channels transistors, particularly the FETs, located close to the inputs. they were dead on channel in the amp I had.

That's all the information I can give you as the amp was repaired quite a few month ago...

Bonjour,

Je n'avais pas vu que tu étais de Lille.

Comme je ne suis pas un expert en électronique et en anglais, est-ce que tu peux me redonner tes explication en français stp.

Merci d'avance.

Ps: j'ai essayé d'envoyer un message privé mais je n'ai pas l'impression cela a marché

I have just bought this amp. Channel 1 is dead and to my ears channel 2 sounds kind of spluttery with the distortion ( 'sustain' ) wound up. Seems like it's possibly the same problem....

[pio]

yes
It is the same problem.
Did you have the schematic?

[momsazombie]

No schems but I know a guy who might fix it and if he does I'll let you know how he did it. Possibly taking it to him this weekend.

Seems like it could be a really nice amp fully working. The effects module has a sweet analog delay. I got it cos I wanted something with more attack than you get from a valve amp.

[pio]

ok

I tell you if I find any information

Hi guys,i have the same problem! What could be the problem?should i change the FET's or what?
