Bose 901 Series IV B Equalize! I bought this as a back up and am downsizing. It was purchased unopened and I used it briefly before putting it away. I have series VI but prefer the (in my opinion) somewhat warmer sound of series III and IV, and it made my series VI sound sweet). The story behind IV B is they only made a very limited number of them as Series IV was being replaced by Series V. I was able to find on line from Bose that the series IV eq supply was used up and they had to utilize series V chassis, parts and cases to make this eq to have the correct series III and IV curve. The best part of it was Bose began to make the equalizers so much better at this time (1983 for this one, the beginning of the series V era) with much better quality everything. It would be a challenge to find a nicer one that this, if you could find one at all! This has some insignificant marks on the case, stains on the box and is really very nice. It sounds warm and wonderful as it should. Dont miss it! Best one you’ll likely ever see!

BOSE 901 Active Equalizer Series II SUPER CLEAN POWERS ON TESTED USED VERY CLEAN, EXCELLENT CONDITION, minor signs of wear. Tested Power, Clear audio signal in and out of Amplifier Connections side I consider myself a pretty competent audiophile, I have a ton of Hi-Fi gear, and have repaired and restored receivers, turntables, cameras, computers, cars etc. I have NO CLUE how this thing works... I hooked up the Amplifier Connections side and it sounded awesome, I could hear some subtle differences in tone when running the dial around. I didnt understand the Tape recorder connections protocol, so I can neither confirm or deny that they are functioning properly. There was audio but it was very faint...
