Birch model 75 78 rpm electric phonograph

I always like it when you post these record players. That Rola speaker is really neat.

I installed an isolation transformer in a small portable record player, and no matter where I put it, it induced hum into the amplifier. The isolation cap never seems to work that great either.

A third option is to cut off the plug, and install something weird like a 2 prong jones plug... then make a little aluminum box with an isolation transformer in it, and a jones receptacle. That way you can keep it (mostly) original, and also prevent unsafe operation.
