Strange problem with Pearl 2 and SAE Cartridge

[McQuaide]

I sketch might be helpful. I have a 1000E that whistles a little when I first power up my Pearl I.

Let us know if it helps.

Is "RL" in the sketch R19 on the Pearl 2 schematic? Didnt make sense that a zobel was strung "across the inputs" but appears that each input has a zobel going from input to same place R19 grounds? Or am I missing it?

Yes.

Yes

The issue is that the SAE is a very high inductance cartridge. The Zoble loads it down so it doesn't ring.

I had the cartridge on my Pearl 2 and it did exactly as McQuaide described without the Zobel, but the fix was easy (suggested by Wayne, of course...) and the problem is gone.

The Cart sounds really fantastic, BTW.

Thanks! I will install before fire up. Are 1/4 watt resistors plenty for this location?

Any resistor would be fine -- the only power it's seeing is what the cartridge can generate.

Thanks for dumming it down for me, much appreciated and saved me freaking out when it wouldnt play right!
