Items are a pair of McIntosh MC40 monoblock power amplifiers. These amplifiers were part of a GS audiometer system (Grason-Stadler, 162K). Slightly different input filter circuit. Both schematics included. I actually used them in my system 'as-is. Used with a hot-rodded Dynaco PAS-3 preamplifier. SPECIFICATIONS & TUBE COMPLEMENT (listed directly from the Manufacturer's website): MAX OUTPUT POWER: 40W FREQUENCY RESPONSE: 20-20KHz (+0.0, -0.1 dB) DISTORTION: 0.5 % SIGNAL TO NOISE RATIO: 90dB INPUT SENSITIVITY: 500mV INPUT IMPEDANCE: 250K ohm (GS input pot is actually 3K ohm - easily swapped) OUTPUT IMPEDANCE: 4-ohm to 16-ohm POWER SUPPLY: 110V/60Hz SIZE: 200 X 206 X 349 mm WEIGHT: 30.0 Kgs (30 Lbs)/Each
TUBES (each monoblock): 2x 6L6GC, 2x 12AX7, 1x 12AU7, 1x 12BH7 ALL TUBES INCLUDED Only selling because I have a Sound Valves VTA-70i, and a modded Dynaco ST-70.
