Rare combination in great working condition. This set is simply stunning and looks fantastic in any setting. 1 Owner from new who purchased it in Australia in 1980. He also had the matching cassette deck and turntable however they were discarded after going faulty. Amp was serviced last year as the volume control was noisy, simple fix with contact cleaner. 3 New blue colored lamps fitted to the Tuner. Sound quality as expected is very good.
