Ha! That's great! Put me in the electric chair!

Ok, maybe not with 10W....

Oh wow, too many great chairs!

Here’s the completed PS filter board, which concludes the stuffing/soldering portion of my program. Next up will be some intensive studying of the wiring diagram and maybe getting some boards on the heat sinks.

My overall feedback so far is that everything has been easy to understand, organized well, and a breeze to assemble. Hope everyone enjoys their builds!

Ps. I received LSK170/LSJ74’s in my kit, and they all measured very tight matches. I wouldn’t sweat it if you didn’t receive the tiny Toshiba’s, as it’s obvious these have been matched well.

I thought Q1 and Q2 were supposed to face each others and zip tied for thermal tracking?

 

[codyt]

You can still zip tie, heat shrink, thermal cap, etc in this configuration. More important is to follow orientation on the silkscreen.

observe other Papamps, and orientation of JFets in them

Papa is not so much concerned with same, as regular Greedy Boy is

The M3's for the top/bottom cover are hex-types.....thread length about 10mm.
It will look "pro" compared to "philips-head" screws.....

+1 yes hex-types are the best

I haven’t realized that I got bad influence from the Greedy Boy.

CodyT - Did Home Depot have all the screws? Or did you have to check Lowes, too?

 

[Zen Mod]

do not worry

CodyT bought entire Home Depot

[codyt]

Nope, no Home Depot trip for me. Trying to show some restraint

Parts arrived today.
Well packed, and sorted parts and boards in separate boxes and an envelope. Very clean and professional. I thought the color wiring in the pdf was for clarity, nope the silipplied wires are color coded.

A public thank you to the DIY Store team!

I did notice a date on the VFET alu plates, it would seem that this project has been incubating for a while already.
Now waiting on the chassis to arrive.
