This auction if for a pair of vintage McIntosh MC-30 tube type power amplifiers with consecutive serial numbers original instruction manuals. I have owned these amps since the early 70's. Prior to that they were owned by my cousin who bought them new in the early 60's. I paired the amps with a McIntosh C-20 preamp which I recently sold. Now I need to sell the MC-30s. As far as I know these amps have all original parts including capacitors, tubes, and resistors. The only part that doesn't look original is one internal cap that doesn't seem to match the others. These amps have been stored for the past few years in an indoor, dry, temperature controlled place.
今、MC30sを売ろうと思います。知っている限りでは、これらのアンプにはコンデンサ、チューブ、抵抗などが入っているオリジナルのパーツがすべてあります。
オリジナルに見えない唯一のパーツは、他のものと合わない内部キャップが1つあります。これらのアンプは、屋内で、乾燥し温度も制御されている場所に過去数年間保管されていました。
They have been used for most of their close to 50 year life and have given excellent service. As with any piece of electronics that is almost 50 years old, these amps show some cosmetic imperfections. All of the lettering on top next to the tubes and on the input/output side seems to be perfect. The large attached metal McIntosh logo on the side is intact on both amps and looks good.There is a bit of corrosion and pitting on the chrome that doesn't really show up in the photos. The sides and edges show more of the corrosion than the top. Looking down on the tubes, the top show slight pitting of the chrome.At a distance and in the pictures, the amps look great.
if you're looking for a pair of excellent vintage amps to have restored or do yourself then these would make good candidates.I have not found a need to do any restoration as they seem to work fine.To me, keeping them original made more sense than trying to make them sonically perfect. Frankly, these 50 year old Macs still sound better than any of my later model solid state stereo gear!
When I decided to sell my McIntosh gear I hooked up the MC-30s and detected no hums or buzzes and was able to get good sounding audio out of them.
If I had the space I would have liked to hook them up and use them again, however, I don't and they're too nice and too valuable to let sit around anymore. Someone who appreciates their quality should get use out of them.The only testing I was able to do was hook them up to speakers and a preamp and play music through them. Other than that, they have not been tested and therefore will not be warranted. You buy them, they are yours.
