Post the 6 digit part numbers & the whole chassis ##.
You may find it here. If not someone will pipe in with any
distributors with OEM NOS parts.
Most of these got bad connections & bad electrolytic inside
the tuner assy. Also bad main filter cans & a few flybacks.
Not much else, they were a damn good set & looked nice on the outside.
good luck
