An amazing’endgame’ classic as used by Brian Wilson on Pet Sounds.

From a local estate collection of several high end audio pieces. This Mcintosh MC240 has been tested and sounds great. I used a small pair of 4 inch full range near field speakers for testing and it really sings. I also tested all the driver tubes, which are a mixed bag, and all are in spec. Output tubes are SED WINGED C. They tested good on my BK-700 tester reading a 74, 69, 85, 89. On the BK the good range is from 66-120. I don’t know when or if this amp has ever been serviced. It was one part of a nice high end sound system for listening to music and/or as part of a home theatre setup. There were multiple amps and speakers and a nice projection system with a movie screen as well as turntables and lots of record albums, just to give you a feel of the environment it came from.

McIntosh MC240 power amplifier in beautiful condition. This is the earliest version of this amplifier released in 1960. The amplifier has been completely restored with new power supply, capacitors, and resistors by Fuchs Audio in New Jersey. The amp comes with 4 NOS GE 6L6GT power tubes, 2 NOS RCA 12BT7 tubes, and JJ 12AX7 tubes. The amp is warm sounding with incredibly deep bass and clarity, even by modern standards.

This unit has undergone an extensive electronic restoration here at Novalux Stereophonic. The unit has also received a fresh set of tubes. There is a McIntosh clinic sticker on the front of the unit which has been left in place for historical context.

Here we have a very clean McIntosh MC240! This was the first stereo amp introduced by McIntosh… This particular unit was boxed up in storage by previous owner for quite some time. I powered the amplifier up very slowly with a variac and it performs like a real champ! There is no hum from the amp and the sound quality is good, but the tubes have not been tested and a new set of quality matched tubes should make a marked improvement. Most of the tubes are Zenith, one is RCA, one with worn off markings. I believe this could be an early production model. I’ve provided the photos which should help date the unit. The circuitry appears to be all original. Please note chassis stamp number 133. Also rubber stamp numbers on inside chassis. Included is a photo of the backs of the potentiometers which should help date this amp. Switches and pots are all working well and sound clean. Chrome is in especially nice condition and silk screen lettering in in very good condition but a little wear on some letters. Also please note that the top left corner of the Right speaker terminal strip is broken and the screw has a larger head compared to the others and was probably swapped out at one time.
