The VP-Gainswitch Resistor Set is a complete set of all required resistors required to add a stepped gain switch mod to any of our mic preamps. All eleven resistors in this set are Xicon metal film, 1/4 watt, with a 1% tolerance.

The resistors included in this set, along with a Grayhill 71 series switch and appropriate adapter PCB, will create an equivalent to a 25kCCW log pot, which is perfect for an API style mic preamp circuit.

With this set, you can expect the following 12 gain steps:

From my tests, the actual gain may vary a little but should not differ more than +/- 0.1dB. The above measurements where taken from a VP26 preamp loaded with a gar2520. This preamp did have the t-pad attenuator installed. An Audio Precision Portable One Plus was the test instrument.

***Please note: Complete Gainswitch bundles including the PCB and Grayhill switch can be found here.
