Adding a Fader to EZ1073

[glazer56]

Hi all,
I've recently bought one of Colin's kits and love it. I've been thinking I would love to add a fader to the unit though to have more control over the output, ride levels ect... My thought would be to build a NEVE switching unit, minus the sends and busses to patch in after the pre. I've looked all over but haven't found what R value NEVE used for their faders, as it's not on any schematic. The other option would be to replace the trim knob with a fader before the output section, but again, need to find what value the fader would be. Does anyone have this info by chance? Working the math has never been my strong point!
Many thanks!

Neve faders were 10K audio taper (Penny and Giles).

Easiest way would be to replace the trim pot for a fader of the same value

what about using a 600ohm t-pad attenuator after the output transformer ? would that work too ?

I would use a 10K trim pot before the output section, easy and simple,
just check Madrianse ez1290 project, the trim pot is implemented there and works great

On the 80-series desk they were actually 5k, at least on the ones i have looked in including the two i own.
