Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

RE: it is better than that...:)

Did you know that simply running only the filament will melt solder?

Now, add the plate current to that.

I once built a good sounding S.E. amp out of one-- until I realized that a good 2A3 or 45 outperforms it. It made a nice transmitting tube-- I've replaced a lot of them in Mil.Spec. transmitters.

Guess what? Dull Cherry-Red is what the plates like. Run an old one at the same temperature, and you'll get nothing! (In a transmitter). They have to be "sharp".

For practical purposes, it's another outdated antique. Today, we have 100% solid-state transmitters with autotune.
