SOLD 3/28/22
Can't edit post title, now $750.
My time with this sweet sounding class A amp has run it's course, and I'm ready for something that's a better fit for my lifestyle. I'm happy to let it go for $750. Shipping should be about $150, I attached a screenshot FedEx ground estimate.
All MOSFETs have been replaced with matched MOSFETs from DiyAudioStore. I have several posts regarding this exact amp on the forums (Illustrated F5 Guide, and F5T Builders Thread).
More details
I can barely hear it when my head was 12 in away from the speakers. I suspected the green AC switch up front may have had something to do with it, and disconnected it, that wasn't it. It's been re-attached, as it's a pretty and functional switch.
I've attached some pics I snapped tonight of details of the amp. If you'd like a link to the Google Photos album of the entire build, PM me.
It will be a sweet amp for someone out there, thanks for looking.

More details
- The chassis, was a group buy from "Ultimate 4U 500mm Chassis" on this forum. Came from Italy, modushop here. I had the front laser etched with (IMO) a really cool subtle text. The front aluminum plate is 10mm thick (took me a while to cut that switch hole in it!)
- Transformer is a bit oversized, Antec AN-8425 - 800VA 25V Transformer (weird! I checked my order receipt it said AN-8225, but the pic of the actual transformer in my hand is AN-8425... <shrug> )
- Cardas XLR inputs, not hooked up
- diyaudio Universal Power Supply, 8x 22,00uF capacitors digikey
- new metal feet for the chassis (ones that came with it were sorta cheesy plastic numbers)
- 2x 3.0a slow blow fuses in the IEC
