Completely overhauled/recapped/serviced/fine tuned Sphere 900 console equalizers stereo pair with custom designed internal power supply. Cosmetically and functionally minty; quiet - mastering-grade.

$5k shipped to the lower 48 states.

Recapped/custom power supply by the veteran geniuses at Rainbow Electronics, and further serviced/calibrated by Ken at Orphan Audio. Detents and buttons are crisp and sharp, these have to be around 50 years old (Led Zeppelin II was mixed on a console like this I believe) and seem as new (military grade construction, built to LAST). Receipts available. I believe the input/output transformers are Jensen. Only selling to make room for some original 511 channel strips but won't mind keeping these forever! * these are the same EQ's as the Electrodyne 712 but with the added frequency choices of 5k and 8k on the 6.4k lever (push-button select) Posted elsewhere.
I have $5600 into these, only selling as I located some original Electrodyne 711 channel strips I want. (if you have 1-2 of those, let's talk!) Joe Grandberg supajc "at" hotmail.com

Bump, very interested in partial trade with UREI 545 EQ from you, very interested in having an RCA 44bx as well, reach out to me with offers. I can be entertained by parametric EQ's in general. PM me your offers!
 
Just to add a little to samplebias2s 900EQs..

The output trafos are real Sphere outputs
These are the same as modern day Jensen
JT-123 series. Can't see the #s on the inputs
so can't say.
