maplins sell one in kit form by wellmann - i've had good results in a sony turntable separate mounting the board in the box and using the motoe dc supply with a smoothing/hum redduction circuit

when are you to send pics of the beocord 3500 deck?

does anyone have a diagram for the ones that are built in to newer decks i.e bg4500/9500.

i have had a look on the net but cant seem to find any (must be me looking in the wrong place?)

You can make one - I think one of our members has done so. However a small external one will probably be much easier - you can get datalink to work using a separate wire.

Hi Mark,

I have to say that I am not very familiar with all B&O record decks, but I do know something about RIAA circuits. As long as there is a DC power supply (like +/- 15V), or room for a power supply inside the turntable, you can build in any RIAA circuitry you like. There are many circuit diagrams available on the internet and they can quite easy be made home as long as you have any experience in electronics.

Regards,

Bart.

hi i was wondering if the RIAA that is built into the modern beograms (i.e BG4500/9500 etc) can be home made and fitted into an older deck (BG3000/3300) if so does anyone have a diagram and part's list?

many thanks
