The Manley 120 Watt Monoblock employs a pair of Teslovak KT88S or the strong Russian 6550C output tubes which can be switched from TRIODE operation to ULTRA-LINEAR mode. This amplifier could also be custom-ordered with the original KT90.

A three position feedback selector switch is provided on the front panel: LOW: 6 dB. MEDIUM : 9 dB and HIGH :12 dB.
