Installed bulk foil resistors in phono amp

I installed four of these Vishay Z-Foil (TX2575) in my phono preamp - the loading and series input resistors on the first triode. Considerable improvement in clarity, image stability and perception of speed. Highly recommended upgrade. PartsConnexion. 4 for $65.

Ralph, there’s a 1k on the grid of the first triode which I replaced as well as the load resistor.

Good. What's the input tube?

I agree, it’s a very significant upgrade to lower resistor noise and inductance . I removed the resistors in the signal path in my Levinson 20.6’s and replaced them with Vishay VAR foils.

Yes, I've heard good things about that tube.
A 10K grid stop resistor will give you considerably more RFI protection.
