    Bogen BR-360 - A curious GW find

    Picked this unit up last night for $15.75 at the Goodwill. It was a diamond in the rough, covered with 50 years’ worth of fingerprints, grime and dust. I could tell that it was in decent shape, It powered up, with dial lights, and it was heavy and mega solid so I bought it. First thoughts...

    Recapped better than spec pioneer sx-1010 or…

    May have the opportunity to trade my up to spec pioneer sx-1010 for a dynaco pas3, st 70, and an fm-3 plus a little cash on my end I could really care less on the tuner. So that’s not a plus to me in anyway. But I have been very curious of tube separates lately. I’m running Cornwalls with the sx...

    I just purchased this unit and know little to nothing about it. I’ve tested various functions (am, fm, tape, phonograph, speakers, power inputs), all of which work well.

    Fisher 28 stereo with BSR changer

    Found at Goodwill for next to nothing. Installed a new stylus...the unit sounds better than it has a right to. Made in Japan...I'm guessing by Sanyo. Has a BSR changer and a Shure M75 cart. All functions working properly. I'd consider this on par with some of the similar KLH units I've...
