Description

Limited stock — closeout pricing.

We have developed a replacement circuit for the Sterling ST77. The circuit topology is a single-stage JFET with output transformer. We have optimized this circuit to create even-order harmonics, which add richness, saturation, and texture to your tracks.

This product is identical to our best-selling T-84 circuit kit, adapted to fit the ST77 chassis.

 

Features & Benefits

The new circuit has lower noise and superior sonics to the original. Combined with the RK-12 capsule, you can build our T-12 mic into your ST77 housing.

The new circuit provides internal switches for a 10dB pad and polar pattern (Cardioid Omni). The pattern switch requires a dual-diaphragm capsule, such as the RK-12 or RK-47.

 

In The Box

You ll receive our T-84 circuit parts (including transformer) and instructions, with a PCB designed to fit the Sterling ST77.

The installation process is slightly more challenging than some of our other kits, for these reasons:
