Well you could always just fake it. At least one company has a ultra small
class D amp with some extra leds that they stuff in a glass tube that looks
just like a medium power output tube.

the amps look so cool. Where are the tubes 🤣?
sprinkle some sand on heatsink, it'll produce a tube in a minute or so
Earned my merit badge last night. 🙂 Seen here installed on (optional) Hammond tube chassis.

That looks really cute. Will it ever be on the store?
Yes, I’m sure they’ll make it to the store 🙂
Looking forward to see the complete schematic for this amp, as I have some nice double C-core chokes in the 50-60mH range that should be just about perfect.
Wonderful. Too bad I can’t be there. And another proof of MZM’s omnipresence:

Forza RS!
I will be driving to RS to pick him up next year, and we will contemplate either driving across the Behring Strait, or using the force to cross the Atlantic. Or both.
We might need a conductor for that. Or zenductor

Hi Nelson, just reading the article in post #169 and checking the parts list on page 5, just a few corrections on the QTY table for some items for a pair of boards.
C1 should be qty 2
C2,3 should be qty 4
Inductor mount screw 6-32 x 3/8' should be qty 8
Inductor mount Kepnut 6-32 should be qty 8
PCB mount screw 6-32 x 1/4" should be qty 8 or up to 16
PCB mount standoff 6-32 should be qty 8 or up to 16. Looks like there are 8 mounting holes around the pcb edge.

Wow Gary, is this the 1st thing that came to your mind after reading the article?
Not for example the choice of the MOSFET or why 12 VDC but this?

A friendly proofreading is always welcome, particularly when there are totally logical corrections suggested.
Trolling, on the other hand, isn’t appreciated. (And against the rules…)

Well, I did read the whole article, then looked at parts to see what I had and found those few very minor corrections - only trying to help all the future builders and no criticism of the author is intended at all.
I am sure both authors have chosen parts wisely.
