Mark Levinson 334 Question

I have noticed there have been a few for sale lately. I know the caps were an issue but does anyone know what the serial numbers were that were mainly affected?  Also what is your opinion on the amp overall? Stay away or take a chance? How long do caps usually last? 20 years or so?

I can't speak to the 334, but the 331, 332 and 333 were all affected.

I had to have my 333 recapped after about 5 years. But it did sound great in my system.

It is my understanding the 334 early on had some cap issues but not sure of the serial number Madrigal corrected or installed the better caps?

They all fail eventually.  It's not a SN issue, it's the circuit design of the 3xx amplifiers that are very hard on the caps.
