These kits are backed by over 25 years of experience in selecting pre amp valves for professional musicians who trust their sound to Watford valves.
Gain reduction 55%

The Fender Pro Junior Harma low gain 55 12AY7 STR kit is designed to give you the cleanest sound out of your Fender amplifier. The 12AY7 was used by Fender as a low gain first stage signal valve in many of its early designs.

By putting this valve the V1 first gain position you will lower the gain of a pre amp circuit by around 55%. This low gain results in the maximum clean headroom for your amplifier. If you are playing humbuckers through a Fender amp, using a 12AY7 6072A is also a great way to achieve the maximum clean tone and the cleanest tone overall.

This valve is also very popular with Harmonica players as the low gain prevents the feedback that many harp players have problems with. This valve produces a warm rounded clean sound with low gain which will give the maximum clean tone and tame the harshest of pre amps.

The kit consists of 2 valves

1 Specially Selected Harma 12AY7 STR for position V1
1 Specially Selected & Balanced Harma ECC83 STR for V2

The Harma valves are specially selected for this kit using very tight gain parameters and
gain selection of triodes sections. The valves are carefully selected for low noise and low levels of hiss and ambient noise with a signal to noise ratio better than -80dBV.
