Attenuator wiring question
« on: 30 Oct 2013, 07:04 pm »
I have a pair of Carver 180 tube amps. Each amp has an attenuator which I don't use but it's the first thing the RCA input signal sees. I replaced them with the GoldPoint Mini V 100k attenuators and noticed a great improvement in transparency even with the GP wide open. I was wondering if I could just bypass the GP and wire direct?? I'm thinking the 100k resistance of the GP needs to be in the circuit?? If so maybe I could just insert some 100k resistors?? If so I'm not sure which wire to put the resistor on - there are 3 wires.

Any suggestions would be appreciated.

A resistor needs to be in the input circuit.
Are you running with the attenuators wide open?

Yes, wide open.

Thx

You can take the pots out of the circuit and install in their place resistors

in-----------to tube grid
      |
     | | resistor
      |
     --- ground

with this arrangement only two wires are used

cheers  :green:
