Default Re: Philips' Rocking Crystal Cartridges

Loading was from my Heathkit S-33H amplifier gram input which is designed around the Decca Deram ceramic and uses capacitive feedback and a 2M2 grid resistor. Amplifier was set to mono, so bridged L&R.

As a crosscheck I also tested bridged cartridge directly into the 1M load of my Heathkit IM-48u. This gave an almost identical response except for no bass rolloff.

Tracking weight ~4 grams
