I have a simulation of an F7 amp for sale. It's not a real F7, and I have no idea whether it sounds like a real one, but it does sound pretty good. I'm just trying to recover the cost of the parts. I have too many amps and this one has to go (it lost out to my M2). You may even want to take the boards out and use this just for the power supply, which is dual to the power cord. Transformers are from Antek, and the power supply is built on boards from the DIY Audio store. Relays bypass the inrush current limiters after 20 sec or so. The idea is to avoid blowing fuses if the amp is turned off and immediately turned back on; probably unnecessary but it's just a thing I do. It has two power switches because I wanted one in the front and the precut back panel from modushop only takes a power inlet with a switch in it. The speaker binding posts are those beautiful rhodium plated heavy-duty jobs from Gaofei; I'm sure they don't affect the sound at all but they're really pretty. I'm asking $700; I'd prefer local pickup (Philadelphia area) but I'll ship it if necessary. Sadly enough that won't be cheap because this bugger weighs a ton.

You may try USAudiomart this would be a steal for someone wanting something special for peanuts compared to what they would spend at a retailer for something similar. I imagine you have more than $700 in this with the dual mono PS and 4U chassis. I would be interested in it for that price if i was closer.
I have it up there too, and on Craigslist. I may try ebay but I don't really want to ship it..........but I will if I have to.
Hi, I have a few questions:
1. What do you mean by F7 Simulation? How did you pattern it after the original F7? Where did you source the parts to "simulate" it?
2. Why did you decide to use dual mono? Does it have an advantage over just the stock one torrodial design (in relation to the F7's stock design)?
3. Could this be converted for 220v/240v use?
4. How much do you think shipping will be to California?

Hello RXV,
1. Some fellows on the forum who are a lot smarter than I am have taken clues from Papa and worked out a circuit that gives similar measurements to a real F7, and made a limited number of boards available, and I used a set of those. The parts came from Mouser, for the most part, and the laterals from Exicon.
2. Because I could
3. Probably - I think the transformers have the necessary primaries, check Antek Inc. to be sure.
4. Shipping to Oregon was around $115, so I imagine California would be in the same ballpark.
