I have a Carvin R1000 that's in need of some work. The head still works fine for the most part. The main issue is that the fan block has broken free on part of the inside and moves around when you carry the amp. I don't know if there's any other internal issues or not (I'm no technician) but it does still operate and produce the sound, volume, etc. as it should. It comes in the fuzzy two-space rack that Carvin sends them in standard. If anyone out there would like to take a crack at it, they can have it for just $25 and shipping (plus PayPal if you go that way). Shipping would probably be about $20, maybe less.
