JRF's PLX line
To offer you even more choices and substantial savings, we have designed our own PLX line of premium quality direct replacement heads. Each head is made to JRF's exact specifications, and combines the latest refinements in magnetic head design with precision craftsmanship and extended-wear materials.

Compared to original heads, many PLX models offer extended high frequency performance and improved crosstalk specs. Mechanically, PLX heads are manufactured to tolerances usually found only in the most expensive heads, with track width and mounting surface to centerline maintained within 0.001 inch. Other features include 0.012 inch minimum tip depth, extended high permeability crosstalk shielding, and 0.002 inch core laminations for optimum frequency response. In most cases, PLX heads may be substituted for original factory models with little or no alterations to electronics.

PLX heads are available for a wide variety of recorders and tape formats, including 4-track heads for Otari MTR-12 and Studer A80MR low-speed mastering recorders for tape duplication.

No matter which heads you choose, you can take advantage of JRF's unsurpassed service. Send in your headblock and we'll spare you the tedious and time-consuming job of removing your old heads, installing the new ones, and aligning them on your own.
