Does anybody have one of these for sale?

Siltronix model 90-3 for Mark III working or not working?
 

Gonna have a few of our "digitized" versions before long. Smoked plex face plate, 6-digit frequency display, buffer amplifier built in so it can drive a tube if need be. A trimpot serves to turn it down for a solid-state radio.

200 bucks plus shipping/insurance.

For now they're lined up on the bench for drift testing. Getting them stabilized is a cut/try, cut/try lather rinse repeat process until it stays within 1 kHz all day.

Found a pic of one from a previous batch.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
