The schematics ought to have the REV field filled in.
Make sure that ZD2 and ZD3 are 8V2...!!!!!

just use SIT Schematic, I drew it with exactly that purpose 
what part you can't see on schematic, don't solder it on pcb, simple as that
it implies being "flying", soldered ditto on SIT gate and heatshrinked with wire to gate pin, so wire not hanging on wimpy resistor pin
solder 47R instead

Yeah, I like that smoke. Is that a SIT caliber gun? 🔫🔥
ZM... you have a GREAT sense of humor. Awesome, don't change. It's a great trait to have. Not enough people have a good sense of humor. If we all had more humor, the World would indeed be a better place.

As I'm doing a parts order I'm wondering if the MJE340/350 is drop in replacement for the bd139/140. You've mentioned using it in next kits. Any reason to not add to my order?
Good eye.
This Antek transformer double bracket uses a nylon shoulder washer to insulate the bolt and avoid a shorted turn. 👍🏻

I’m looking at heat sinks. Looks like the price of aluminum goes up. How many watts will the SIT version produce in heat, normally biased, per channel?
Thanks pal. So a 0,36 W/C sink will raise 22-23 C over ambient. That’s not much to write home about is it?
Ps. Looked up the Modu, it’s 0,28 C°/W. All sorts of standards when describing them. That’s about 17-18 C over ambient.
The one I was looking at is a 300x300 that would comply with my form factor preferals

Made an order so big the alu smelt works up north almost drained the grid.
Also building a dummy load hopefully big enough to test all the transformers in my iron stash that would give me in the vicinity of 2x24 vac to see what they are good for.

@Vunce That's a real looker you have built there!
I don't have the skill to tell if you have a speaker protection circuit hidden at the back. Having enjoyed the wrath of the SET version...I wouldn't run this amp without it. No offense meant to the designer. This is a fabulous amp. It's even 'hot'.

That was a single heatsink that I cut to the dimensions needed to fit a pair of R25 psu’s. Don’t remember where I got it from?
Yes Soren, this amp will have DC speaker protection and maybe thermal protection also. (If I don’t get lazy during chassis wiring)
