Re: Phono Transfer System Construction Information

For both 15 and 30 IPS?

I see what I think is a bias trap in the preamp front end.

Re: Phono Transfer System Construction Information

Based on the termination resistance (56K) I'm wondering if the MM board would be a better option.

Re: Phono Transfer System Construction Information

Paul -

I'm not sure I can read the values.
What is the value of the resistor that terminates the head?
Is it 56K?

Re: The Studer "90° Filter" Stereo to Mono Summer/Recorrelator
