This is a pair of the legendary Mark Levinson mono 33 amps, rated at an extremely conservative 350 watts for each mono amp. (these are the 120 volt version) These have been totally gone thru and revamped from top to bottom by one of the best qualified Levinson techs (maybe the only one!) on the West Coast (Seattle area). We can fix them when others can't! Caps were replaced and the units were fully tested for days to make sure everything was 100%, so no need to fear getting a classic amp on the verge of breakdown! This work cost the owner about $2000, so it was not a "basic" rehash, but a complete rebuild of any critical cap or part that might go bad!! I have the paperwork to prove! These are in good to very good condition with a few minor defects but overall in at least good shape. The only drawback is I do NOT have the original crates, so either crates will need to be made, or you will have to pick these up in one of our stores. I can have them delivered if you'd like to any location in the general Seattle/Tacoma area. (an extra delivery fee may apply depending on your location.) If you have a truck or van and some strong help, you can also arrange for pick up. These amps are powerful and will drive any speaker made and deliver superb results. NO tubes to ever replace, just sweet, natural sound with superb control! I can certainly demonstrate these, but will need a bit of notice to get them to one of our stores and hooked up to a great system. Price is for the stereo pair, of course! Bank transfer or credit cards preferred for payment. Paypal adds 3%.
