What can I build with 2 CV4007 Tubes?

[TheBigMan]

Been raking through my box of old Military Spec parts.  Doing quite well so far, 40 NPN Germanium trannies and various other bits and pieces.  Just found 2 CV4007 tubes as well, idly wondering if they are suitable for one of the low voltage tube boosters that are floating around.  I know absolutely nothing about tubes.

That's funny, I'm thinking the same thing !!
I have a bunch of Mullard M8099 ( CV7040;'s ) which is a mil-spec 6AQ6
Mini 7 pin pentodes, which I think can be used in one of Doug Hammond's valve
overdrives ... ??
I'm guessing due to the size, that a "pair" equates to a damm fine 12AX7 ...

cv4007 will not amplify. it's a diode.
6aq5 can be used as a power output tube. use it instead of 6v6 in a champ design i have one wired like that, sounds nice. different from 6bq5 and 6v6 altoghether. check out www.ax84.com see their p1 project.

Aha, mine are 6AQ4 and have a B7G base .... ??

Guess I'll just have to fit them into the feedback loop of a Tube Screamer then.

Don't do that!  Make a tube-based octave up instead.

OR an Electra distortion! One triode, two diodes!
