Some time ago a CLM Dynamics DB500S Expounder came my way in non-functional shape.
The toroidal transformer was detached from its mounting point, though its wiring was still connected. The numerous boards appeared undamaged.
A thorough search for Allan Bradley, the Expounder's designer and former owner of CLM, came to nowt. Likewise, the company in Aberdeen that did CLM's assembly has vanished.
I reached out to PMI (they now own Trident), reasoning that since [ed. 'the other'] Alan bought out CLM to obtain its patents, PMI/Trident would surely have a schematic for the Expounder.
This made sense, as PMI used Allan Bradley's patent to design the Trident Hi-Lo dynamic equalizer.
The PMI tech with whom I corresponded told me that he didn't have a schematic for the Expounder, and wouldn't risk a repair attempt.
A tech in Watertown MA was recommended by a fellow Gearslut, so the CLM DB500S was duly consigned to his outfit, Audio Proz.
Seven months have passed, with no evidence of any progress on the repair.
Do any of you perhaps
a) possess a schematic, or
b) know of a professional tech who has worked on the DB500S?
At this point, I'm ready to admit defeat.
Best regards,
Rohan
