OUTPUT TUBES:10 x RUSSIAN 6550
The 6550's used are the Russian Svetlana 6550's. This has been proven to be the rugged and reliable of this type and
we strongly emphasize that only the RUSSIAN 6550's should be used in this amplifier. The MANLEY 440/200 WATT
MONOBLOCK 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 TUBE: 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.
