I’ve just taken delivery of a really tidy Orban 622B equaliser. These are great, useable 4-band equalisers with per-band bypass switches like a Klein & Hummel. The example has all-original knobs & switches and looks like it’s been tucked away in a box for the last thirty years
I’ll be refurbishing this with new caps, upgraded power supply and replacement of the troublesome Tantalum caps with electrolytics. When it’s ready it’ll be listed here. Update soon!
