Default For Sale: MoFo monoblock amps

Two monoblock MoFo (mosfet follower) amplifiers are for sale. These amps will generate about 20 watts per channel. They are built on Michael Rothacher's design (see the build thread here) I strongly recommend you read the description of the amp if you're considering buying; it's funny as hell if nothing else! I'm selling these for less than the cost of the parts because I have many more amps than I need.

Spike feet will be included if you want them. There are inserts for them in the bottom of the amp, or you can use rubber stick-on feet.
I probably don't need to say this here, but I will anyway: Mosfet followers are amps that have current gain but no voltage gain, so you need to have a preamp with a significant voltage swing. If you don't then they won't play very loud. You are welcome to come by to give them a listen if you live near Philadelphia.

These have the large Hammond chokes; the original design was only 10 watts per channel, but double that is possible with the larger chokes. The power supply is a Meanwell 8 amp computer PSU, which is a much higher rating than needed. Highest quality parts are used throughout. The sides and front are palmwood, and I had the back panels specially made by Front Panel Express.

My carpentry skills aren't the best so one of the front corners doesn't quite join right; you won't notice it from the front when they're sitting on the shelf though. I'm going to try to reglue it.

Asking $295 + shipping. They'll be shipped in separate boxes; shipping probably won't be cheap as they're heavy and will have to be bolted to a board so they won't shift around.
