This Listing is for a Classic McIntosh MA-6100 MA6100 Stereo Integrated Amplifier. The amplifier is in good working condition and has just had a tune-up from a highly qualified technician who replaced some capacitors and also a problem child with the Ma-6100 and that is the on and off volume control. The volume control was from McIntosh and cost over $100. So this amp should be set for many more years of quality sound reproduction.

I have taken quite a few pictures with very bright lights which show up pretty much any blemishes on the amplifier. So the cosmetics can be viewed in the pictures.


Some of the Specs for the amplifier are as follows:

Power output: 70 watts per channel into 8Ω (stereo)

Frequency response: 20Hz to 20kHz

Total harmonic distortion: 0.2%

Damping factor: 50

Input sensitivity: 2.5mV (MM), 300mV (line)

Signal to noise ratio: 76dB (MM), 90dB (line)

Output: 300mV (line)

Speaker load impedance: 4Ω to 16Ω

Semiconductors: 36 x transistors, 22 x diodes, 2 x TRIAC

Dimensions: 406 x 138 x 330mm


Due to age the amplifiers are being sold AS IS.

Disclaimer: When buying almost 50 and 50 plus year old electronic equipment that has not had all parts replaced with new parts there is always the possibility with failure to the 50 year old part/s at any time. Some of the electronic part/s may continue for another 50 years without need of replacement and some electronic part/s may fail a few days after you start using the item. The item will arrive to you in the working condition as described in the listing but I am not responsible for what might happen to the electronics part/s after the item is received in working order due to the age of the electronic part/s.

The buyer pays for shipping and handling/packing, there is a small international paperwork preparation fee of $25 for each package being shipped outside of the USA.
