[quote user="PapaBear"]Hi, I just took my beloved Beogram 8000 out of storage and cannot get it work. All the lights come on, the speed indicators seem to want to work, the play, stop, and tonearm postioning controls also work. But the turntable platter will not rotate. Everything was in perfect working order when I packed it up 6 years ago

Personally, I've never cleaned my Discwasher brush with anything besides the pad cleaning brush which came with it. However, I haven't cleaned many records which were moldy. From what I've read online, dish soap should be sufficient to clean records which have mold and mildew, so I don't see why it wouldn't be sufficient for the

[quote user="Piaf"] Thanks Adam, Perhaps I will just really clean the old brush and keep it. With 7 Beograms it can not hurt to have more than one cleaning tool. Jeff [/quote] Yep, it's definitely nice to have several cleaning methods available, especially when one's vinyl listening stations are spaced far apart. I use a Stanton carbon

Actually, those who use Discwasher brushes actually prefer the old brushes to the new ones. The older ones have microfibers which are contoured to ride parallel to the grooves, while the newer ones just have uncontoured felt which doesn't work as well. As long as the old brush isn't worn out, I don't see why you'd have to throw it away

[quote user="mafanni"] Hi, can anyone help with fitting an RIAA amp internally to an BG 5500. I own anoriginal B&O RIAA for build in, but do not know wher to put it. Thanks [/quote] As far as I know, there are no provisions for an RIAA preamp to be fitted within a Beogram 5500, as the Beomaster 5500 it was made to go with has an RIAA preamp

Glad you were able to fix the problem. I've never messed around with using two turntables on the same phono input, but I'm glad you were able to find a solution. I'd still compare the switchbox with using a single turntable on a single input, since I'm concerned about signal degradation due to the low voltage and capacitance levels involved

Yep, definitely a ground loop; the results with the 8000's ground disconnected proves it. One option is to build a separate switchbox for the ground leads using a single-pole double-throw toggle switch with each turntable ground lead connected to one of the outer terminals, and a wire from the switch's center terminal going to the switchbox's

Does indeed sound like some sort of ground loop. Which input was selected when you removed the 8000's ground wire, and the hum went away? Did hum go away for one, or both? I've seen amps with two grounding screws and two phono inputs, but I'm not sure if they ground to the same place or not. Grounding one to the 4500 might help, but I'm

Most ground problems I've seen involve hum rather than hiss. My guess is that the hiss is due to using a switchbox; using a switchbox to switch two turntables is usually discouraged, due to capacitance issues and/or noise. If you're going to use a switchbox, use an inline phono preamp between each turntable and the switchbox's inputs, and

[quote user="Peter "] Loose internal connection - could work for years or could break permanently tonight! [/quote] Probably. It definitely didn't seem "loose" when I was using it; the effect was there, and didn't seem at all intermittent. The effect was similar, if not identical, to the MMC5 I got with my Beogram TX 2 with
