Perfect,
I like the rectifiers mounted to the front panel. I am always surprised at the amount of heat they produce.

Very neat job Jeff! Pre-amp is? And what source & front-end do you normally use?
Really happy with the sound?
Have a great 2019.

Thanks, guys!
@brianco, it'll be fed with Roon through a Metrum Musette. I'm building some Troels Gravesen TQWTs for it; judging from the output over my test speakers (some old Gale 4s, which aren't particularly efficient) I don't think I'll need a pre at all. It sounds bloody marvellous!
I'm in mid-Louth, between Drogheda and Dundalk.

Beautiful, Jeff! My question is, what enclosure are you using? Where did you get it?
Congrats!
Remodeled the psu on my f5 turbo...6 x 47000uf, first 4 are ROE golds, last pair Sikorel. Had 6x33000uf nippon chemi 32d in it before.
Sound has changed, though not dramatically. Smoother, a little more laid back and liquid. Perhaps the caps will break in some, I did reform them first though.

Finished my amp a while ago... this is from the day I controlled the bias a second time... after that some cable arrangement has been made. Still need to get brushed and anodized but due to heavy workload and house renovation there is not enough time...
Amp sings like a charm, pretty heavy though (roughly 40kg) built from 5mm top and bottom, 3mm back, 15mm sides and 25mm front. Will replace bridge rectifiers with diode rectifier at a future time.

Very nice result!
Hello Fabian85,
this is avery nice VFet-Amp! A lot of aluminum involved.
I think the milling machine was screaming for a long time? 😀
And then drilling and tapping for all the screws.....
Enjoy it!

I am within a group of diy'ers... or lets say I am doing all the electrical work for the group. But I am blessed to have a metal worker access to a huge array of CNC machines, so most of the work was done to my request. Sadly he doesn't do any finishing, so this has to wait for some time...
@Zen: what ur not liking about my terminals?

Hello diyAudio-members,
this happened to me last night. I thought some UFOs have landed!? 😱
AREA 51 in Germany???
But it was a listening session with the BA-3 poweramp and the diyAudio/
Passworks active crossover....
I am laughing about myself.
Cheers!
