    80's Technics Integrated Amps

    Thanks Baily. Will have to check the relay area. BTW- it turned on again earlier this evening and ran as if nothing had happened. Strange, as it hasn't started up for like 2 months... it probably knew that I needed my Floyd fixxx... Also started to go down Baily's rabbit hole- just bought...

    80's Technics Integrated Amps
