asharrow Posted January 2, 2017 Share Posted January 2, 2017 Happy New Year ! I am doing a few minor repairs to my old Marshall JCM900 4502, replacing noisey pots and jacks, etc. (it's time ). The front panel channel switch with built in LED indicator has also been working intermittently so I want to change that out also. This company has most of what I need other than this channel selector switch with the built in LED. http://www.amprepairparts.com/marshall.htm Any recommendations where I could find this part? THANKS VERY MUCH ! Link to comment Share on other sites More sharing options...
asharrow Posted January 2, 2017 Author Share Posted January 2, 2017 I found it: http://www.tubeampdoctor.com/en/shop_Switches_Optocouplers_Switches_Optocoupler/Marshall_Channelswitch_PC_Mount_JCM900_illumin_1779 Not a USA supplier though. Would like to find a US supplier. Thanks. Link to comment Share on other sites More sharing options...
tulk1 Posted January 2, 2017 Share Posted January 2, 2017 Can't help on the parts. But nice that you posted links to parts for the JCM900. Just got mine back. Well, got one like I used to have. Noisy pots, as well. But figured to go the spray route first, then replacements. Cool amps, eh? Link to comment Share on other sites More sharing options...
asharrow Posted January 2, 2017 Author Share Posted January 2, 2017 Good news ( I think ) , I started search the web with different key words once I knew what I was looking for. I found a replacement, measurement mine in the amp with verniers and dimension-ally and contacts it is the same and found that Mouser electronics has them in stock under $5. I ordered it today. So I am hopefully all set. Funny you posted the same Marshall amp model. My 4502 was my main gigging amp from early 90's until 3 years ago. Serviced me well. If this replacement works, I will let you know. Link to comment Share on other sites More sharing options...
