Got it right after changing one jfet and one mosfet,but still it neads at least 2 more gain for the DCX to drive it to the max.There a guy in Sweden working on it.(Ludo,thanks)
It's alive !!!
It's alive !!!
I finshed the assembly this evening, and fired the sucker up !!!
I was petrified ! Worried that I'll blow my speakers. Worried that I'd missed something and see the thing go up in smoke. Worried that it'll be a hum machine, or noise noise noise.
None of that 🙂
I turned it on, no hum ! Attached a preamp, and turned it to max, no noise !!!
Attached a source (after lowering the volume 🙂 ), and music !!!!!
I was ecstatic ! I've spent probably a year or so collecting parts for this thing. Three months or more building it (baby steps, didn't want to rush this one !), and it all paid off !!!
Pictures to come (in my haste, there are no photos of it dissassembled), but I've still got to drill and attach the front panel (10mm alumminium !).
😀 😀 😀 😀 😀 😀
DIY is ******* awesome !!!!!

Hey you guys, I friend is making an F3/V9 .
He has the Peter V9 circuit board. Is there a parts list cross reference
listing what F3 components replace what V9 component or maybe more clearly expressed , is there a parts list for the F3 with the parts numbered to correspond to the parts on the V9 ?
Or is this true already?

Mark,
How about a source for matched power jFets used in either???
I thought it would be cool to make one of these until I figured out that the transistors were made out of the rare metal unobtanium.
Sometimes I am too late to the party,

LU's
Chris,
Check this out. This guy has 600 PowerJfets.
I have ordered a few. A buck two fifty each. Cheaper than most output tubes.
Maybe enough purchasers, assuming these are the real deal, can convince Peter to make some more boards.😀 😀

Lu for sale
Unfortunately, he doesn't have time to sort them out so we'll have to get bigger numbers for matching. But at only US$2.50 ea, it's quite reasonable.
Makes me really appreciate the extraordinary job that Grey did with the Group buy.

It is nice that he has the unobtanium Fet's. I'm going to start a tube amp soon and am redirecting my resources. I bought some efficient speakers so the call of the SET is strong.

There is no problem with more boards. If there is enough interest in 50pcs or so, I can run another production, same for F4 and PS boards.
F3 PCB
I would be in for Z9, F3 PCB set with power supply.
I would by another stereo set of F4's as well. I fried one channel pretty hard.
Shall we start another Wiki Page?

I think I may have done this correctly -
Peter , you may want to review the original commentary and edit.
Others may want to add to this list.
We should only cross reference after a few agree that this is presentable and do-able. I would consider adding instructions if I felt more confident about the final visual outcome we want.

Anyways, here is the Wiki Link.

So Peter, or anyone else that knows- Are the F3 and V9 identical circuits with different value parts? Can I build my V9 boards as F3's with no modifications?
F3 has few more parts for fine tuning, but the circuits are basically the same.
