Rectifier used in HMV 2022 Record Player.

[Old Sparky]

This afternoon, I carried out further tests, firstly with a stack of 45s, then with my test record. In both cases I measured the o/p from the pickup at the amp's i/p, getting variable readings of up to and over 1v with music discs, and steady readings of 1v or more from the tones on the test record. I didn't , however measure the o/p power, but there is plenty of volume available, so i consider this, at last, a finished job.
