Selling my beloved mono's since the upgrade bug bit me. Cosmetically probably a 7 with some nicks and one having one bottom corner bent in a bit. Just been professionally serviced by Hi-Tech Audio and had all values checked anything out of spec was replaced with new, all solder joints reflowed, all new electrolytic caps with the main power caps upgraded from 15,500uF 75 v to 22,000uF 100v computer grade caps so they should be good to go for another 20 years or more. Stock rating is 200w @8 ohm 400w @4 ohm and stable down to 0.75 ohm. 150 amp reserve capacity

I'm throwing in a nice set of power cables and if anyone needs a Dreadnought to run these I can throw in a 750 vA one with speakons for a couple hundred more.

These do make a low "wump" sound and dim your house lights when first turned on.

These have the remaining warrantee.
Edit: these have the optional dual XLR balanced inputs

    Also not sure if this matters but these are consecutive serial numbers. I bought them from the original owner who used them in his recording studio but didn't do that any more. I've seen these for sale for about half this cost but they are old amps. They stopped making these in I believe 1993 so they are at least 27 years old and the older electrolytics get the more they degrade the sound. I have maybe 100 hours on the refresh so they probably need more breaking in. Also these really start to shine after being warmed up for a couple of hours.

    If you were closer I'd drop them off for you to audition. I'll probably rotate them back into my system in a couple weeks just to make sure I'm making the right decision. I still think the Belles just doesn't have the same low end torque that these have but everything's a give and take right? If I don't find a good home for them I'll probably have to move them into my barn system.

    I believe that is for switching between single ended or balanced.
