Very cool, Walter.

Very cool looking arrangement.

buy two adequate sized Rotring radierer gummi , and glue them in between Donuts and platform

Rotring, eh? Boutique stuff...

 

[massimo]

...Also upgraded some components... new better European NTC's in series in the softstart.

Which model, Walter?

P.S. Beautiful build! Congratulations

 

[Zen Mod]

yup

EU NTCs are usually better than US drek

Walter:

Beautiful work, as usual. In fact, it's insanely well organized and neat. Is your therapist concerned about your OCD?

Regards,
Scott

Ah, OCD.....found it...

 

[WalterW]

Walter, fantastic, professional and beauty.
Some questions, where you got the heatsinks?
You cut the aluminium bars, then machinate to they and Finally you anodize ?
I imagine that CSX1 is hard to beat...Do you think the same?
Best Regards
Esteban

Anodize ? No that's chemicals and voltage...too dangerous
Just spray paint with primer, matt black paint and a sealer.

Heatsinks are from Austerlitz: https://www.distrelec.nl/elfa3~nl_nl/elfa/init.do?item=75-626-71&toc=20476

And you are right CSX1 is not to beat....It's the best sounding amp I have.
Sound is so natural, flowing. Instruments and voices, they sound like they are actually in the room. Soundstage is big.
I guess SIT is the audio gain device.... I hope to hear one day Papa's SIT-1 or SIT-2. They must be stunning.

Love your wiring. Never any excess. Always neat and tidy.
I have learned a lot from looking at pics of your builds.

Thanks Dude, I will finish soon the mine.

 

[WalterW]

Very curious for your build
I haven't seen much VFET's builds here, the article is around a year old and there are initiatives for PCBs but a complete amp is rare

 

[nashbap]

Walter,

Have you posted pics of your VFET build? If so, could you direct me to the post #. Now that I have completed my F5TV3 I am thinking of tackling A VFET build.

Thanks.
Paintwork is excellent; look anodize.
Are you mounting your Fets (this build and others) directly onto the painted surface?

 

[WalterW]

No, the heatsinks are not painted, I always buy them black anodized.
