So I have the JCM 600 2x12 combo with an Accutronics reverb unit (2 springs). Lately the reverb was kinda moody, sometimes it was working sometimes not. Then I read some reviews of this particular amp and people were also complaining about the reverb and some suggested to buy a new RCA cable, which connects the reverb unit and the amp. I did that and now there is no reverb, but turning the reverb knob does change the sound. I checked the springs and they look OK. Does anybody have a solution? Thanks a lot!

Re: Reverb problems with my Marshall JCM 600
My problem was w/a Marshall DSL 100 reverb. Sometimes worked, sometimes didn't. Eventually it just stopped. I just replaced the reverb tank. I think the whole job cost under $40. It would cost that much to have a tech look at it probably. Anyway, look at the tank, you'll see what looks like a serial number. It's actually the model. Go to the Accutronic web site to get the actual model then head for the "Antique Electronic Supply" web site. Find your reverb. I think mine came to $36. including shipping. Just screw it in, connect the rca's-done. btw...I took a tank out of my JCM-600 and used it in my DSL till the new one came in. It wasn't exactly the same unit but it worked fine.

Re: Reverb problems with my Marshall JCM 600
i've got exactly the same problem with my DSL401.. the sound changing when you turn the knob is a good sign though - that's the response as when you have a working tank unplugged. the amp itself is ok!
might order a tank now actually, i miss the lush sound
