My personal amplifier. Has been went all the way through. New main filter caps, new switch, new fuses, larger power cord, new electrolytic capacitors on both main boards, new bridge rectifiers on each power supply side. This is the model with the Toshibia Mosfet devices. They have all been removed and brand new Bergquist thermal pads have been installed. This amplifier has not been hot rodded. The amplifier parts are all retained as stock as in values and such however only top end best quality components were installed in place of the stock old parts. Cant recall what all else. In nice very nice condition however it does have scratches on top cover. Have had it out of use for a while as I bought BK Components M 200 mono blocks to use instead so I took it and set it up and made completely sure it still works 100%. This amplifier has been tested. Has almost unreadable DC offset on fluke multi-meters.The amplifier is quiet on both channels and no loud thump on turn on or off. You get it as is, dust and all. It has been an absolute pleasure owning and listening to this amplifier. My B.K. M-200s do not sound better. You will be hard pressed to find a better sound unless you pay 10x the cost. Made In The USA. Any questions you have please make contact with me before you buy. I will be glad to answer as I have been selling on eBay as well as other places on the net for a long time and I have an excellent reputation and intend to keep it that way. Lets see. 400.00 for a good used B&K EX-442 with the Toshiba Mosfets (if you can find one let alone this nice) and 200.00 to restore it (if you can get it done for that, I doubt it) plus shipping of 50.00. Thanks for looking at my advertisement. Will cross post to FB Marketplace and probably US. Audio Mart. 650.00 plus tax. No refunds. Too many parts pirates. For specs go to: https://www.hifiengine.com/manual_library/bk-components/ex-442.shtml As always thank you to Hifiengine for the specs.
