Otari Pro


T/REDS™ 2" Universal

IN STOCK. Originally $575.00/set - now 15% off.

"End-of-Life" ALERT! We've completed our absolute final production run of T/REDS. There's still stock for now...

T/REDS capstan & tach rollers for all OTARI MTR-90 series I, II, & III recorders, and MTR-100's. Cast molded with a stunning red, proprietary elastomer, these are quite simply the best looking, best performing rollers available!

Manufactured in the newer universal style (set screws offset from center) and supplied with special brass tipped set screws, T/REDS may be used with absolutely all MTR-90 & 100 series machines.

When installed with a flutter analyzer, T/REDS are the only rollers which may be rotated and safely locked in any position on the capstan shaft to minimize rotational error and optimize flutter performance.

Recommended: add a pair of 2" swingarm return springs for just $9.25 (regularly $12.75).

Just wanted to let you know that I received and installed the T-Reds yesterday and man do they run smooth.

They even handle the thick ATR tape beautifully!! Installation was easy.

"Do-it-yourselfers" note that PMW is not responsible for motor failure due to improper field installation of parts. The servo-disc must be installed with proper clearance above the "flux return plate" and must be set with a "feeler gauge" or shim. The proper specs will be provided to you.
