I went through a similar experience with my ML332. Came down one morning and it was softly buzzing through the left channel. I took it to the Service Bench in Norwood. They were very nice, but told me it would cost $2,500 to repair. I purchased a replacement set of capacitors that were advertised here on Audiogon by my new amplifier repair sherpa Abe. With his expert help and advice I replaced all the caps and my 332 sounds better than it every has and I saved almost $2,000.
Buy the caps from Abe and you will fall in love with your ML-332 all over again.
