Howdy!
Bought a PRR-176 Rev2 PCB and I want to skip the op-amps on the input and use an attenuator for input control. I have a large amount of LL1527 that I want to use if possible. https://www.lundahltransformers.com/wp-content/uploads/datasheets/1527_7xl.pdf
I drew this attenuator up after studying some alternatives and the prices for rotary switches.
I know that it would be incorrect impedance at 0 dB but I believe the problems will be neglible.
Would this work? If not, how can I make it work?
