Mattes-Martin SSD-1 Preamplifier

Mattes-Martin SSD-1 Preamplifier

Made for only a very short period, less than one year

Incredibly well engineered unit

All ceramic switches

Stepped and variable volume controls

All important I/O’s available from front or rear panel via switches

Commercial/military build and componants

I’d like to hear from anyone that has one. So far I have not located another one
