Here it is.. It looks better inside than out

Currently in Amplifiers / amp repair with a picture. I meant to put it under Amplifiers / amp repair / pro series repair but something went wrong..

Currently working on getting to "Novice" so I can post pics... last night and this morning wrestling with getting the main circuit board out. Must be some mysterious force holding it in. Wish the service panel underneath was a bit wider - tose rubber spacers melted all over the board, under where I can't get to. Time for a bar of Solvol on the fingers

Here's hoping I get there!

Hi All, I found this site when I bought a partially functional PM600 with the aim of learning more about the amps and possibly fixing it. My history with Carver amps is I bought a Carver 1.5t and later a C4000 preamplifier when I left university in the late 80s, to drive my JBL L112s. These are largely the cause of my poor hearing in both ears now. Nowadays I have ME amplifiers and Duntech speakers as the main hi-fi but I am very interested in getting the PM600 going and watching those LEDs dance. One channel works (sort of) and I was hoping to debug it a little more with some hints from members of this site. I have a dual channel CRO and a Electronics degree (but not much practical experience). Just having had a bit of fun in my sparse spare time finding out how the amplifiers work (with the triac driving the transformer) from the service manuals. I also now realise just how old these amplifiers are now.... time moves on quickly! And I ain't getting any younger either.
