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:

I welcome comments and thanks for looking!

Very Nice. May I ask where you got parts from.(Caps etc).
I got a 332 that needs a overhaul.

The main caps are available from Mouser.com
They are about $85.00 each. Part No. 598-3186GJ503M125DPA.
They are not exact replacements for the orginal Phillips caps but they meet or exceed the rating of the originals.

All the other smaller electrolytics were purchased from Mouser or Digikey.
You will not find exact replacements for small signal caps. You have to find suitable replacements with matching or slightly greater voltage, equivalent capacitance and equivalent size.

Mouser and Digikey offer a grid where you can filter down and find the appropriate replacement. As capacitor technology has advanced quite a bit since the late 80’s you will often find equivalent caps in shorter, denser packages. Mouser and Digikey offer top quality Nichion, Panasonic, Illinois and CDublier caps so choose your poison and then bring that glorious M.L. beast back from the grave.
