What could ya build with these giant twin triodes ? ? !

Hiya,
They are a slightly different version of the 6AS7 which is a real impressive and pretty looking tube.
Lots of 6AS7 designs out there.
I like the look of these ..

EDIT:: Even better article ..

Check out the power supply in this http://gilmore2.chem.northwestern.edu/projects/showfile.php?file=barbour_prj.htm
I used a 6AS7 but a 6080 is a direct sub.
I made this preamp just as shown. I used the zener string instead of 0D3 tubes. It's a very nice sounding preamp, works very well as a headphone amp also.

I've got a bunch of those laying around. It would be kind of cool to built a SET amp with only one power tube...
True dat, I've got 3 HH Scott 265A monoblock amps with the 6080 as a pass regulator for the power supply - two 5U4G's and outputs of 4 x 1614/6L6G's to handle.
All of the 6080s that I have are pulls from Tek scopes - they used several of them per scope in the bigger units as voltage regulators.
My Pete Millete Low-Mu preamp runs the 6AS7 and I suppose the 6080 could run in it as well.

Use the American version of the 6080. The Russian tubes seem to be noisy. They are great for headphone amplifiers. You might get 7 watts of audio out of one.
Definitely a good voltage regulator tube........Uncle Sam had many orders for these used in the older comm equipment and test equipment

hey-Hey!!!,
There are also the bigger cousin, type 6336. Then if you want to step up the mu, type 6528, 5998 and 7236...lots of uses for these 'not-for-audio' tubes. The 6336 and 6528 are about the limit of what you can run through an octal socket contact in terms of heater current at 5A though...
Now if you want to up the plate dissipation on the 6336, back off the heater input; the plates will do a fine job of heating the cathode( or at least making significant contributions ). IIRC one could drop to 3A of heater input if you wanted to run 40W from each plate.
cheers,
Douglas.

Bottlehead crack headphone amp clone?
BTW, I don't put the 6080 in the 'big tube' category. You should hang out with the RF crowd a bit....

Hiya,
So looking around these seem to be well suited for OTL designs particularly the 6336.
Fun stuff for sure in the "Junk" tube box. Makes me wonder other than those massively useless TV HV rectifier tubes which for sure don't have a decent use.
But that is another subject.
