the amps look so cool. Where are the tubes ?

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.

sprinkle some sand on heatsink, it'll produce a tube in a minute or so

Put your hand on the sink. You'll swear...it's a tube.

That looks really cute. Will it ever be on the store?

 

[Michael Rothacher]

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.

Attached is the Zenductor article. Hopefully 31 pair will get built at BAF this Saturday,
and a discussion of it will be included in my talk on Sunday...

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

I will post guide-like photos in a couple of hours. I just got home from a trip, airline out to CA tomorrow morning.

@andynor

do not worry, I already have a ride arrangement for next year BAF

 

[Fuling]

I like this amp, I'll definitely build one. Kind of taking the gravel road to 2A3 SET territory

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?

 

[6L6]

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…)

 

[gary s]

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.

 

[MEGA_amp]

WOW! Thank you Nelson and Mike, and of course 6L6! Looking forward to this one for sure!

I was surprised by the very tube-like THD, so I am curious to hear how that sounds.
