ok, here's an update. I replaced the two 10ohm fuseable resistors which are feeding the two 15 volt regulators. As suspected they burnt out straight away. Both regulators are good. To cut to the chase, the issues seems to be in the pre amp board at the front of the amp. When I disconnect the +...

I know I did wonder myself

Oh terrific!!!!! That's exactly what I was looking for!!!! I suspected, as I said in my original post, that they were fusable resistors of a low value, you have confirmed it. I have e mailed Gk tech department.. You say you found this on line, cold you please send me the URL link to it. Thanks...

Unfortunately it's a different model but thanks so much for trying. Rog

Thanks so much, I did find this but is a different model. I got quite excited when I saw it but , alas it's the wrong one.

Thanks for that, if I mange to get a circuit I'll post it on this thread. Rog

Here are some pictures of amp, I have pointed to the two resistors I would like to know their correct value, R15 and R16

I will post a picture later on to make sure that we are talking about the same thing. My interpretation of a "module" is a completely sealed unit and therefore unrepairable. This pcb has descrete components and I've already identified the fuses, the mains bridge rectifier, smoothing capacitors...

Hi there thanks for the reply, I think you must be thinking of a different model amp, there is nothing moduler about this amp. There are three pcbs , a narrow one in the back ( where these resistors are) which also has the intput and output sockets, a main board with a switch mode power supply...

Hi there guys, i'm a newbie on this site. Are there any teckies on here. Ok the story is this, i'm a retired tecky and also play in a big band. Our bass player shorted out some leads, speaker leads I think on his Gallien-Krueger MB200 ( i understand there are two models of this, his is the one...
