charcoal gray, 2 large, 4 small, screws, very good condition-like new, condition #9
Special kit of black, anodized knobs with a shiny finish. 4 small, 2 large. Unique, custom set for prototype audiophile version. For in house use, requires special fit onto shafts. Very sexy! Like new! Condition 9+
(1) Complete back panel assembly with 120vAC connector. Excellent #9 condition.
2 large, 2 small. Typical grey anodized knobs. Used but real nice. No obvious scratches. #8 condition.
Rack mount version, green and black color. No handles included with this piece, but some may be available here. Good #7 condition with three or four long scuff marks in middle, but acceptable for someone who needs a rack face.
10k ohms X 2, detented control, #279Y10Kx2, 6 legs, 5/16" shaft length, 10 available, new, condition #9 (the listed price is for 2 controls)
FYI:
These are fine detent (click) controls. They may be more accurate than the program channel balance you are sending through them, actually. To improve "scaling" of the control, a 2.2k to 4.7k resistor could be put in front (series) with the control. This would probably allow that at the average listening level, the position of the control would be about halfway up.
But this level of audio really also depends on what signal preamp levels come before, and what amplifier gain or input impedance you have after the control. Such matters of level are usually more inaccurate here than with the control itself. In a Japanese preamp like a Nikko Beta 1 (uses same part), control tracking accuracy is within .5 db channel to channel balance. But passive control designs often are inaccurate, subject to matters as mentioned above.
It seems ironic, but passive circuit audiophile designs actually are not as accurate or as quiet as the op amp buffer IC pre and post the control. These controls can be wired in as a true gain control also (not a simple level control) and now frequency bandwidth, impedance matching problems, etc are all solved. But a passive control is OK as long as you are not trying to output a tube preamp to a tube in amp whereby the impedance and signal load matching is now usually a mismatch. It can be a problem to get everything right. Here is a case where probably you must "pre load" the control with a 50k series resistor! Tube preamps by design need to see this minimum requirement "load," FYI.
