Finally making some headway on the 841 amplifier, just been so damn busy lately! I started mounting some of the parts. This thing should come together pretty quickly.

The recessed socket mounting came out really well. Not gonna lie, it looks real dope with a pair of globe 841 in place.

What do you not understand about resistance in parallel?

Traffic on a one lane road will move much more slowly than traffic on a 2 lane road.
It was intended as a joke.

I always pictured you as more of a kilt man myself, or a pleated skirt if listening to Manson.
Marilyn Manson requires tighty whities to prevent possible interference with the air guitar. :smile:

Thanks for sharing that. :ksc75smile:

Today I should be receiving some LS 50 Telefunken power tubes, WW2 vintage to try in my power amp formerly known as Cowen thanks to the kindness of @Old Deaf Donkey.

Seriously, I'd vote for keeping the name of that amp. Cowen sounds noble!

My vote is to call it 'The Sorbothane Amp'. For some reason Sorbothane is Bill's Kryptonite. :stuck_out_tongue_closed_eyes:

Here are the filament and mains transformers before and after shielding. Gives you an idea of what the final look is going to be sans tubes.

Special thanks go out to @Old Deaf Donkey for some 1942 Kriegsmarine Telefunken LS 50 tubes for my amp, sometimes known as the Cowen. :ksc75smile: I will plug them in after a company Zoom meeting and see how they do. They are obviously NOS and the pins are in remarkable shape.

I won a bet using Russian tubes so now it is time to reinvest some of my winnings into the amp and to see what the Telefunkens do for it, driver and power tubes.

I have not read back far enough to know, is that a kit or did you have the top cut for your own design?

It is my design, the chassis and layout were done in AutoCAD then machined. First time I've done the entire layout without the chassis in front of me, but seems to have worked out well!
