Seem to remember reading somewhere that one of these two amplifiers that used the 3-400 that you could not slap a 3-500 in. It was something about the chimney height and the height to the top of the case or something. You couldn't put the taller tube in. Does anybody remember exactly the case...

Still playing with your boards? How did it work out? I'm shocked I stumbled on this thread so late .

Because they're all 50 years old. They've all long since died and rotted into the ground. I mean it's not like they're a couple years old

Link?

I disagree. I enjoy the maul dropping .

Oh that's interesting. The 800 is such a cool tube. Now I wanna see it.

Yeah it's probably not. Very interesting then

@Jay Mojave come on brother, make a comeback!

Somebody had mentioned there was a particular amplifier project in that issue that would Interest me but I can only assume it was likely a multi band 3-500z amp... If it was I don't care. If it was more exotic though ....

Anyone got one on hand?

Speaking of filament chokes, not that this is my thread, but on the same vein of thought... I learned the coupling effect to the chassis the hard way. I pretty much suspend every filament choke now just off the surface of the deck. However you can do it is useful...in tube amps of course.

I'd put the grid connections back to stock. Leave Teddy's work alone.

Plus it adds capacitance to the circuit which fucks it up for various reasons. It can couple in some cases and to the uninitiated can rock their world. same thing happens when guys mount a filament choke to the chassis.

Can you take a relay out of its little plastic box and use that?

Oh .yeah one other observation is that the problem with wierd length coaxes is more evident with a reactive load. Alot of issues go away when you are using a totally non reactive load like a dummy load/purely resistive load
