I'm currently looking into a Fisher 400C preamp for restoration.
I have the schematic for the preamp. and it seems to show a loading resistor of 110 K ohm for the phono input ?
I thought that 47 K was the standard value.
Was there a number of different values in the past ?
The Fisher 400C was made in the early 60's (I think).
