resident	yes I had visited dr.tube with no results due to some problems he had with his server(ISP).   I sent him an e-mail asking for help and he was very helpfull!!   Today he sent me the schems with an e-mail.   Very nice person! I didn't have any contact with him in the past.

Hi Enzo,   Yes I'm the same person.Thanks again.   Dr.Tube sent me three files...you send me four...so I have the missing (reverb PCB) now.     I have posted to diyaudio some more problems I have.   I'm searching for a good European marshall dealer.   IC6 is missing!!! It's a dual switched mixer op-am(i think).I'm trying to find it.It's coded as M5201 or 5201A (mitsubishi).   I also need three pots.   Any help on this?

I am a Marshall dealer, so I just order such things from them. Well, from the US distributor, not direct from JMP. Not sure what you do in Europe. I have never bothered to look elsewhere. I have to think it is available somewhere, it isn't a custom part for Marshall.     Is only IC6 missing, or are there some resistors and things gone too. Without me looking it up, what does that IC do in the amp?

anonymous	Hi Enzo,   I ordered the parts from a dealer over here.   Thank you very much for your help!   The sad thing is that maybe I bought them a little bit expensive.   Only IC6 was missing (it's something like a dual switching op-amp)and three pots that the previous owner had replaced them with other kind of pots!   I bought the pots at 7 euro each(!) and 3 euro the 5201A,without VAT.
