Perfect Timing !!!
6L6, all my parts show d up today so I just looked on DIYAudio to see if you had started on the build guide. Low and Behold here it is ! Fantastic job. Looking forward to your updates !

First time i thought about it in detail 😀. The case of V-fet will most probably have connection to case/safety ground via the screw. So why do we use a mica washer?
Mhm, i must be wrong, but in my thinking connection to ground is given even with washer because of the screw and all metal housing of V-fet.
tnx,
stefan

The pinout of the Vfets is here -
An externally hosted image should be here but it was not working when we last tested it.
Mica is used as we don't want to have the Drain connected to chassis ground.
😀 😀 😀
@6L6
tnx : ), what i ignored, was the fact that screw is isolated against alloybracket via PCB at the bottom. Screw touches PCB and not the bracket itself!

@6l6; Hi Jim, how hot does it go? Is it more Aleph J (hot) or more F6 (warm) like?
I wonder if 30cm x 10cm (or 12cm) is sufficient. Guess your build has 30cm x 15cm?
happythanx,

Warm. But remember that there is no such thing as heatsinks "too big." 😀
The Aleph J is certainly much, much hotter.

thank you 🙂, I do have my "variable" FW-Fn chassis with bigger heatsinks. But since this one has other rail-V and therefore other PSU it´ll get it´s own new case.
Also i´m shure there is some more 24V FW-Fn entertainment to come 🙂 so that ol´ big case is not in retirement.

Apologies if this has been answered elsewhere, but can the universal power supply board be used to power this amp? Im debating whether to butcher my F6 and re-use parts. My F6 is in a 4U case from Modushop. Are you using a 5U in your build pics 6L6?
All resistors minimal ratings are 1/4 watt´s with one exception 0.1 Ohm are 3 watts.
Resistors watts rating can be little biger versions but not smaller ones.
Example 0/5 watts for all and 5 watts for 0.1 Ohm.
Best regards 🙂
Hi. Speaking of power supplies, if I go with monoblocks, what is the recommended value for reservoir caps ?
7500uF each or stick with 15000uF ?
TIA.

Hi 6l6,
Excellent guide.
I found this forum a couple of days ago! I can't believe I could have missed this chance ... I hope I can get one of the batch 3 kits. Your guide will be a great help.
Thanks

33000 uF each x 10 pcs is cheaper
Go for psu with " muscular force " 🙂

isn't more safe to use 50v caps for the psu? i remember to see somewhere this recommendation and 6l6 has it on the psu diagrams as well.
