I live in the Pacific Northwest and am looking for some recommendations on good shops that will accept mail-in repairs. Has anyone heard of R&R Communications in Wilmington, DE? How about Walcott Radio in Walcott, IA? Do they do good work? Are their service fees reasonable? I am looking to get a tune-up and peak , add some colored LEDS in the meters and channel readout to a Robyn SB-520D. I just purchased this radio on Ebay recently and it looks super. It seems to work OK but I want it checked over before I start using it full time.
