Record Players

I have always loved record players. Me and my mum used to drive around the county attending different flea markets, in hopes of scoring old record players. I tried to fix them, but I did more harm than good.

Denon DP-50F

The Denon Direct drive automatic record player DP-50F was relased in 1978, costing 98,000 yen with plywood plinth. The player is a real marvel at least for someone interested analog control technology. The Denon Museum is full of techspec and information Imported from Japan, i have Recaped it with nichicon audio caps, and it is all greased up. In almost perfect working condition however, the stop point for the tone arm drifts with temperature. Yes, I know that one cannot sonically improve a record player by changing caps in the speed regulator circuit. However, they are gold and just look splendid! Thus easily worth the extra 10 cents. You can get a manual for the DP-40F, from It’s basically the same internals.

Yamaha YP-D9

The yamaha YP-D9 was realased in japan only. The plint is made out of particle board. I’m waiting for mine to arrive from Japan...
