Looking for Amp Repair - Midwest USA: ALS-500M mobile amplifier that is inoperable, needs repair. Would like to find a reputable repair technician to do the work in the midwest so shipping is reasonable.
So Who is doing reputable and timely repair work on these ? Pls only reply if you know they are in business and taking repairs -- I posted a similar query elsewhere and got three suggestions two of whom are silent key and the third was no longer repairing Ameritron amplifiers now that MFJ is out of business.
Thanks very much !; Listing #1755076 - Submitted on 01/07/26 by Callsign K9UR - IP: c-68-50-9-236.hsd1.in.comcast.net; Click to Contact -- Send this Ad to a Friend
