Hi,
I have a fully finished F6 for sale. One of the most universal diy FW amps if you ask me. Selling it because I desperately want to finish other long going projects and need some cash to push it. As you can see on the photos it is a very clean built (I have a bit of old about it so clean solder joints, all flux washed off, parts aligned etc 🙂. It uses a bit bigger 5U 300mm chassis I got from Italy. PSU uses Primrose audio grade 400VA transformer. As you can see all wiring done with the connectors so you can later on put another FW boards into it if you want (sorry no pre tapped holes though). If you have any questions, please ask. Price is $1000 + PP fees + only US shipping (maybe it is not even at cost nowadays with all the prices went up). Thanks for looking!

you are welcome. I am looking for a best box and planing to ship it in the next couple of days. Will message you my PayPal info.
Due to some miscommunication and some confusion about multitude of FW amps sale did not go through, so the amp is still for sale.
w/respect. I'm wasted cost? Whoops! meant to say west coast . wa. state. 'nice build'. -I'd like to hear it prior to buying- ;not possible. Bye.
Looks like a wonderful amp built with well-chosen parts and a generous chassis with plenty of heatsinking.
Do you mind providing the info below?
What JFETs?
What output devices?
Size and voltage rating for PSU filter caps? Looks like they're rated for 85C.
Toroid with 18VAC secondaries => Rails ~ +- 24V?
Cheers.

Thanks for your message.
So...
1. JFETs are Toshibas J74/K170
2. The outputs are IRFP240/9240. I'd say those are Vishay from the look. Those are from the batch we bought and matched with one diyaudio member like 8 years ago so my memory is a bit cloudy, sorry for that.
3. Caps are 22k uf, 35V, 85C
4. 400VA 115/230V, 18VAC
This chassis is quite big for this amp so the sinks stay at 45is C.
