[HomeBrew] Octal equiv. of 12AU7?

Mon, 7 Jul 2003 19:47:00 -0500

The 6SN7 is equivalent to a 12AU7 in that it is a medium-mu dual triode.
The 6SN7 of course only takes 6.3v on the filament and at a higher current,
0.6A.  My listing doesn't show the plate dissipation.  As a resistance
coupled amplifier, I think the 6SN7 would do the job, especially at audio
frequencies.  The 12AU7 might do better in RF applications, especially at
VHF.

Pinouts for 6SN7:  1-GT2, 2-PT2, 3-KT2, 4-GT1, 5-PT1, 6-KT1, 7 & 8 are
filaments.

The 6SL7 is another dual triode, but its High-Mu.  Would probably do the job
in a lot of applications.  The pinouts are the same.

A 6SQ7 is a single triode with dual diodes typically used as detector, AVC
and first audio.

What are you brewing?  Motivation for going octal cosmetic?

suspect it is one of the 6S*7 series (6SQ7, 6SN7, etc). Let me know and
thanks. Cal, N6KYR.
