Trident Audio 9066B 3-Band Equalizer (Vintage)
Checked and in good working order. The unit has scratchy/crackly pots, but due to the nature of their sealed design, they’re unable to be cleaned/serviced properly. However once dialled in, the sound is not compromised, only when in use is the issue noticeable. The unit shows some clear signs of use, including marks and scratches commensurate with age.
The Trident CB9066 is a fantastic sounding 3 band 80 series style parametric EQ with sweepable hi and lo pass filters. It features bypass, bandwidth control and 16 dB of boost/cut on each of the three parametric bands.
The unit’s designer John Oram discusses the design philosophy behind the 9066 B:
“This was my first product designed for the original Trident company when I was hired as a design consultant in 1974. It’s discrete using tons of tantalum capacitors that the company had inadvertently over ordered. I created a unique frequency sweep technology giving a 10:1 range with a single gang pot. Totally class A with BC413 and BC416 devices in the main running on a +45 volt rail. Trident liked the design and the fast turnaround and I continued there on a project by project basis for 14 years. Designed long before I did the Series 80 circuits, it’s interesting how that sonic footprint carried through in my later designs.”
