  • T202 consistently runs about 20 cents flat

    My T202 has been consistently running about 20 cents flat for a couple of years now.
    Regularly oiled.
    Never done a flush though.
    Main TWG shaft can be spun by hand.
    Any thoughts?
    Current:
    1971 T-202 with Carsten Meyer mods: Remove key click filters, single-trigger percussion, UM 16' drawbar volume correction. Lower Manual bass foldback.
    Korg CX3 (original 1980's analogue model).
    1967 Leslie 122 with custom inbuilt preamp on back panel for 1/4" line-level inputs, bass & treble controls. Horn diffusers intact.
    2009 Marshall 2061x HW Plexi head into Marshall 4x12 cabinet.

    Former:
    1964 C3
    196x M-102
    197x X5
    197x Leslie 825

    Have you checked the motor bearings for possible binding? If the TWG spins freely the issue must be on the drive side. Try disconnect the TWG and check the running of the motor without load. I have a T222 running beautifully. Does your one also make that "Whooosh" sound on startup?

        I would guess the same as Enor's reply, but it's also interesting that a 60Hz USA machine played in, say, the 50Hz UK and rewired to C... will also run the best part of 20cents flat. 16 or 18 cents, I've forgotten exactly how much.
