Vox Berkeley and Cambridge Bullet MRB Switch 1960s - Brass over Nickel Vintage Preh Germany Brand

NOS Vintage Preh Brand Made In West Germany 6 Pin DIN Jack  for MRB Berkeley and Cambridge Thomas Organ Sepulveda California Vox Amps

Background: Vintage transistor Thomas Organ Berkeley and Cambridge 6 PIN DIN Jack Amps has the MRB feature but it "CANNOT" be activated without a 3 Button footswitch as the MRB is a hidden feature that cannot be turned on by the front panel like it's big brothers.  Here is a simple solution to activate your hidden MRB feature without spending a ton of money on a 3 Button Footswitch.  Your MRB Feature must be functioning as this switch only activates it if it is in working condition.

Note: We Quadruple Check our build for continuity. If your MRB Feature does not activate with this switch, it is not our switch but your amp!  Have a tech on the back of your amp use a jumper wire from Pin #4 to Ground, if this activates your MRB then this switch will work. 

The Bullet Switch:   We acquired a large quantity of NOS German Made brass nickel plated 6 pin Din Jack made by Preh from of all places the Whirlpool Corporation Parts Distribution.  When Thomas Organ went out of business it was Whirlpool who purchased the remaining stock and parts. Preh was the German Brand used by Thomas Organ for their Vox foot switches. Although these are New Old Stock, there are signs of very minor blemishes from storage with other Din Jacks but hard to tell.  

This build: This works just like the original foot pedal. However, this is a "latching" switch unlike the original which was momentary. Press once from "ON" and Press again for "OFF". Safe to be left in place and compatible with the Series 90, V1143, V1142, V1141 Super Beatle, All Royal Guardsman, All Buckingham, All Viscount and the 6 Pin DIN Jack version of the Berkeley and Cambridge. 

Note:  This will NOT work with Vox amplifiers made in England by JMI - Rose Morris - VSE - Rolls Royce etc.  It must be a "Thomas Organ" VOX product made in Sepulveda California.

Shipping  is Free within the USA.   

Techs:  This is a latching switch. Push Once = Off, Push again = On. There are two contacts: Pin 4 is the "MRB" contact and the ground contact is the nickel housing.  The backside of pin 1, 2, 3, 5, and 6 have been clipped at base and removed to accommodate wires. Safe on all Vox Thomas Organ amps with 6 Pin DIN Jack.
