The amp is in great condition! All of the tubes look like they should and the metal is pretty clean with only some light pitting on it. See pictures for more and feel free to ask any questions! I’ve also included an invoice from an authorized McIntosh repair shop and the man who worked on it had worked for Mcintosh for 30+ years and knew them very well. The repair was minor and the goal was to have it work for another 40 years. The customer stated fault at the bottom of the document is misleading. There aren’t any problems at all with the power supply. This comment was made to the repair guy because that’s what my co-worker said happened to it. My diagnosis was unfounded and a guess. It ran like a champ when I used it! Also, the owner’s manual included isn’t the original but rather a copy of it that I have used.

Vintage Organ Tube Amplifier. To use the gearhead expression “ran when parked”, it did work before I put it storage. As you can see, storage has not been kind to it. This unit has 1x 5U4GB Rectifier, 4x 6BQ5 / EL84 power tubes and 4x 12AX7 tubes. This amplifier is a prime candidate for a sweet little conversion project! The last 2 picture are from Worthpoint to show you what this looks like shined up. This is in Louisville, Kentucky.

This particular set tests strong and are closely balanced / matched. The print on these tubes is fragile and will easily rub off, some has already rubbed off, special care was taken not to rub off any more while testing. The tubes’ test results are displayed in the photos (New 12AX7 Spec 100% = 1,600 Gm). See the photos for physical / cosmetic condition. Notes Regarding Tube Tests. All tubes are tested on an Amplitrex AT-1000 tester in the automatic Fixed Bias Mode (for the most conservative results). Test Results are for a general reference only, and are not a guarantee of performance, nor a guarantee of how they will test on your tester. No real world (audio) performance measurements are taken.

Vintage Single Ended 12AX7 6BQ5/EL84 Stereo Tube Amplifier no 300B 2A3 El34 KT88

Vintage US made El84 single ended stereo integrated amplifier for DIY restoration project or for parts. I was thinking of using the chassis for a DIY pre amplifier or DIY phono stage project. However, This vintage amplifier looked too good to kill just for chassis. So it is better to save it as a stereo tube amplifier. The transformers are excellent, worth more than the price asked for the whole thing. Bought from someone taken out from working console ten years ago. It is time for the next new owner.
