Here is the story on this amp. I bought a lot of 24 condition unknown devices. I am an Electronic Technician but only have so many hours per day to devote to repair. I could not locate any schematic for this amp. In order to provide information to aid in you valuing this item I tested all the output transistors for shorts. NONE of the output transistors are shorted. I did not test any further. I did test the - and + power supply rails on both sides. They are both identical. That is where I stopped. This item DOES need to be repaired! Both channels are distorted and sound like some sort of motorboating. All the transistors are the original ones as manufactured. I did not notice any component that was overheated. This is a VERY CLEAN MOST EXCELLENT APPEARING AMPLIFIER. It is built like a TANK! The front panel is like 1/2 thick. It is one heavy beast. I do not offer any warranty whatsoever. I do not accept any returns for any reason. Check my feedback please. I do not sell junk. This amp is NOT working properly. Selling AS IS. I will ship this item either FedEx Ground or U.P.S. Ground INSURED. ADDITIONAL IMPORTANT INFO: Buyer agrees that, in case of damage in transit occurs, that buyer will supply as many photos as carrier requests to document shipping transit damage. Buyer further agrees to save ALL packaging material used to send this item. On Jun-23-24 at 08:04:14 PDT, seller added the following information: I am surprised in the extreme amount of interest in this non working amp. I would like to tell viewers that I have FOUR Threshold monoblock amps arriving here soon.  I believe they are 100 WPC RMS or more. They would be available for pickup only by either a buyer or a representative of a buyer. I would sell 1, 2, 3 or all 4. Oddly enough these 4 are unrelated to this one. Message me if there is interest in the monoblocks and I will try to list them here on ebay. They are not as pristine as this one. I believe they weigh close to 100 pounds each.
