Yaaaawn. Removing tone controls from a piece of Eico lowest-common-
denominator tin of elcheapo. A more creative act would be to throw it
in the skip. A complete and accurate description of your big project
would be "snip-snip a coupla wires". The rest is shrinkwrapped waffle.

My latest project is to complete some modifications to an Eico 2080
integrated amplifier, which uses 7591s in PP configuration, and is similar
in many respects to the ST-70 circuit.
Among my goals we
1. To install a remote volume control, using the very nice kit sold by
Mikkel Simonsen, formerly of R.A.T.
2. Remove the tone control circuitry;
3. Design a new faceplate for the reduced number of controls.
In order to achieve goal #1, I used one of the tone control tube positions
as a cathode follower, to drive the 50K motorized volume control. Mikkel's
circuitry included a driver for a mute relay.
I am housing his circuit inside of a metal box installed under the chassis,
to reduce interference as much as possible.
A schematic of one channel the proposed design is posted on:

I welcome any comments / criticisms / suggestions on the proposed design.
Thank you.
