Modifying my Mark Levinson 332 for a unique visual experience


I bought a Mark Levinson 332 in very bad shape. It had some serious internal problems and the exterior was showing 30+ years of neglect. I wanted a Levinson amp since I was a teen but there was no way I could drop that amount of coin on an amplifier. Well after 30+  years this amp has finally found me and we have been friends ever since.

Internally is was a mess. It needed to be fully recapped, needed various components that were exploded and needed a complete voltage gain board that looked like it served a few tours in Iraq. After I made the repairs and dialed in all the adjustments all was good in the world.

An amp of this magnitude is not only an aural experience but there is a visual experience too, right?

Time to tackle the cosmetics. Initially I was going to repaint the covers that were faded from sun or smoke exposure. There were some ugly scratches in the paint too. I decided to strip the paint from the covers with acetone. I didn't realize that the top cover was some top quality aluminum and it was beautiful once the paint was gone. The TIG welds were precise and the surface was smooth. That got my gears going. I was going to take it to the next level and have a unique amp that no one else on the planet has. I was going to polish that high grade aluminum to a mirror finish. The front bezel received the same treatment, as well as the power button, which to my surprise was aluminum as well.

This amp pays tribute to so many other high end amps like Dynas and McIntosh that have some meticulously polished frames and hopefully it is one-of-a-kind. Others suggest that modding it in this manner will drive resale value down. That is not a concern for me. I think this amp is a keeper and now that it is polished I fell in love with it all over again.

Here is a public link to a photo of it:

Wow you did a great job, looks fantastic. I have owned just about all of the Mark Levinson 3 series. They are great amps, using a 335 now.

Thanks! for sharing- generatorlabs


Beautiful pic. How did you originally come across this amp? What year was it built?


Happy Listening!

Thank you all for your kind words!

I bought it online with the knowledge that it was not functioning. I don't have any history on the amp but I do know there were very crude attempts at repair which probably caused more damage.  The vaporized voltage gain pcb is probably a result of amateur repairs. I am not tooting my own whistle here; I am far from a professional audio technician. I had more questions about how this amp worked than anyone! I did take my time and used sane methods to troubleshoot. An amp with power reserves like this is like a lightning bolt. It demands respect and we just have to keep that lightning controlled. I knew an amp of this age was going to need a recap anyway, so why pay premium for a working device that would probably need work? At least this way I knew it was done and could I document it. I also did many of the performance and safety enhancements that ML deemed necessary. As for the year it was built...I am not sure. There is no implicit date stamped on the back. There is only a serial number of 1618. I don’t know what the production rate of these monsters was but to me that number seems fairly low, so it could be an older unit. Thanks again.
Very nice remodel indeed. Though I've  a number of the ML pieces, I'm also not greatly familiar either. I'd just think it was supposed to look like that. Very beautiful; great work. Hopefully it sings for you now.
Wow! That polished surface is awesome! Kudos!

I seem to recall there was a problem with the original caps in early production models with that series anyway, so you're right to be ahead of the game than with a "working" resale.

I had a ML 333 years ago. A real beast. Two things I did that greatly improved performance were a custom stand from Sound Anchors that greatly improved bass and a dedicated 30 amp line that made it sing with ease.

Don't worry about resale . . . enjoy!
