I bought this Sound City guitar amp project on eBay. No tubes. 1 broken potentiometer shaft. Transformers are thought to be good, which is significant, because these vintage Partridge transformers are about $400 each. I paid about $285 for the entire chassis. Make me a reasonable offer. I have to move, and I am realizing I will never get around to this project. Definitely a good deal just for the transformers! Almost any output transformer for 6 EL34's is going to be expensive, and so is the power transformer. Some people like to convert the preamp into a HIWATT design, a rather popular mod because it results in an incredible sounding amp with very little noise, a very Gilmore / Who sound. Buyer pays shipping. I have not cleaned it up at all, everything is as I got it. No signs of any water or other catastrophic damage, no signs of any burns/fire/etc. I can take pics of the fully-populated eyelet circuit boards too if anyone is interested. A REAL STEAL!

Note this was a Reeves design from right before HIWATT; you can see the lineage in the chassis layout etc.

It's all there except for one insulating input jack and the power pilot light, the pots are all there but one has a broken plastic shaft. The bat is broken off of the power switch. It's definitely rebuildable or worth far more as parts than I'm willing to take. It's got reverb in & out jacks in the back. I've got a small Sound City logo panel I'll throw in. If you're interested let me know, before I put it on eBay. Your location is important, as shipping will not be cheap.
