OUTPUT TUBES:4 x RUSSIAN 6CA7/EL34

The 6CA7's used are the Russian up-rated 6CA7's. This has been proven to be the rugged and reliable of this type and

we strongly emphasize that only the RUSSIAN 6CA7's should be used in this amplifier. The MANLEY DIRECT INPUT 50/50

has been thoroughly optimised around this tube. Use of unapproved tube types can and will void your warranty.

DRIVER TUBES: 2 x 6414

The 6414 is an American military uprated version of the 12BH7A with increased current drive.

INPUT TUBES: 2 x 12AT7WA

The 12AT7WA has several equivalent numbers, (12AT7, 12AT7A, 6201, ECC81, etc.) Any of these types may be

used. We have selected this 12AT7WA very carefully for noise, microphonics, and constancy. Replacement tubes of premium

quality are always available from MANLEY LABORATORIES.
