Amplifier two line Mk 4

Stereo integrated amplifier, line 2 x 75 W

 
Amplifier2L-vorne
 

Design * Construction

· full tube technique in the signal path
· pre amp / power amp discretely usable (operate intern/extern)
· volume regulation by processor controlled relays and fixed resistors
· volume adjustment with high resolution and wide range
· all functions relay-controlled (no capacitve influences by signal cabling)
· anode power amplification
· triode or pentode operation (switchable)


Front panel rotary step switches

· input
phono (-Amp), CD, 2 x tuner, 2 x line
