Default Re: Restore a Beau Decca

To describe the hum...

If you take 1 to be very quiet and 10 to be very loud, and a moderate listening volume to be level 4, then with the deck playing music and the volume level set lowish, the hum level and the music level are about the same level and combined are a level 4. If you disconnect the deck the hum gets much louder- about a level 6.

I've now disconnected and checked R50 and it appears to be faulty. The meter shows infinite even at the 2000K and 20M scales.
