Technics SU 3500 Stereo Amplifier 1975

Technics SU 3500 Stereo Amplifier 
1975

The amplifier from Rainer Collection


This item is originally my first first stereo amplifier bought in 1975. I've got it back from my school friend now. As a collector I'm very happy because it is still as good in shape as I sold to my friend around 1980.
The amp provides 55 watts pc and that's enough for rocking the whole house and neighbors. A three-stage impedance matching for phono input is something special. Two phono inputs were already standard at Technics amplifiers.
