Pre-owned in perfect working condition. (Remanufactured by Bryston c.2016) Vintage Bryston 4B 250w Professional Power Amplifier- Balanced XLR and TRS inputs - Serial # 412641 HISTORY Owned by my father who did live sound for decades. He is retiring from being a sound man all his life and Im helping him sell off some of his equipment. This Bryston 4B was sent out directly to Bryston in 2016 to be gone over and remanufactured. This was a $500 charge alone to have the capacitors updated, the output transistors changed, etc..and given a clean bill of health. (see last picture of receipt) Since the update, this 4B has been sitting in storage for a few years and has seen little use. CONDITION Condition wise, this beast of an amp is in good overall condition with a few scuffs mainly to the top of the unit from sliding this in and out of an equipment rack. The face plate is in very good condition for its age with only a few minor blemishes. All heat sink fins are in tact with no broken edges. This amp is fully operational and is ready to go into your professional audio setup immediately. With it being serviced in 2016, you rest assured knowing that this 4B will be the reliable brute this industry has known to love. Shipping This unit will ship within (1) business day of payment. A signature confirmation will be required upon delivery . This a requirement by eBay due to the high value of your item. Returns We guarantee this amp to be fully functional for 30 days. Fully functional means normal operation. Any user error resulting in catastrophic failure will void any warranty period. All returns must be made within 30 days of purchase date. If you have any problems with the amp, just reach out to me and my father directly. We are here to help.

Bryston D250Z famous multizone / theatre amplifier. 8 channels. Note, see image - zone 3 and 4 are not currently working. Bryston has diagnosed as a mute system repair (the unit is automatically turning on mute for the 2 zones when it shouldn’t) and offered an RMA. I’m going to list for 1 auction cycle to see if someone would like to buy it at a steal and can handle the RMA with Bryston or self-repair it. Otherwise I’m great working condition. The zones that work are fantastic and have the classic condition of power, clarity, noise floor, and control that has made Bryston so famous. Please ask any questions before bidding. Will ship via FedEx, with insurance paid by me. Happy bidding.

Bryston 4B 250 Watt 2-Channel Power Amplifier Unit is in working order. Ships FEDEX, CONUS only. Worldwide shipping via ebay international shipping program.
