SL-1200 MK2 loop filter mod?

A 33k resistor and 470nF cap in // with the cap nearest the lower right edge of the board according to SoundHi-fi is a worthwhile sonic improvement as it removes some low frequency oscillation. I just fitted it and am not sure I can hear any difference yet but the platter certainly takes longer to return to speed if you slow it with your finger.

I've removed it as the pitch stability was clearly worse.

Thanks for the feedback. I was going to ask you for your source so I could study up on the circuit before trying this. This may require a scope to properly tune the circuit.
