RT-909 Calibration needed - UK/Midlands

[BlueMeanie68]

Hello.

Does anyone in the UK know of somebody who can calibrate my RT-909?

Just re-fitted some re-lapped heads. Torque adjustment would also be beneficial.

Midlands area would be good or within a 150 mile radius of Derby.

Please PM me if you can help me.

Cheers

Did you ask on Tapeheads.net. There is a good UK contingent over there that might know of a tech.

Torque adjustment shouldn't be too hard. With a spring scale, adjust potentiometers to gram readings on the scale.

Great.. I will do that.

DYI Audio forum also may be a resource. At lot of helpful folks on it also.
