    Technics SL-1401 needs some love

    Hello folks, I'm dedicating some attention to my Technics SL-1401 to do some maintenance. The turntable was bought by my dad new in 1978, I started using it at the age of 4 (in 1991)... and it has been in continuous use to this day. I ask you if you can help me, I have 3 questions: 1)...

    Ringing Garrard Model 82

    Hello, I have seen a number of forums on deadening ringing aluminum platters, but the use of rubber mats and felt and Plastidip rubber coating has had zero effect on this turntable. I cannot find anything that would be scraping the platter, and I have used a couple of different idler wheels...

    Adcom GFA 555 II - AC fuse question & fuse holder needed

    A fellow gave me is subject amp today for free. He only said it does not work and that he changed the fuses. Upon inspection: - the switch in back was in mono-bridged position, so perhaps why he thought broken - the fuse in the AC fuse holder is a 20A fuse, way above the 12A spec. Two...

    Fixing Grace 707 Damping w/ Pics

    When I bought my Luxman PD121, I quickly noticed that the tone arm lift handle's O-ring had broken. Chunks came out followed by dripping damping fluid. Quickly thereafter, the damping was gone. Searching online, I couldn't find any guides other than a 2007 post on DIY Audio (here). But, that...

    Revox B790 underdamped speed regulation

    Hello all, I have a Revox turntable in working condition, I've replaced all the capacitors, diode bridges and whatever is reasonable in such an old machine, the regulators I remember, in practice all the components that Revox experts recommends to change. The speed is OK, from time to time...
