Mini-Choke™ Factoid

A Mercury Mini-Choke™ replaces a resistor and adds a discernable amount of tonal dimension to the circuit.

Chokes were originally used in vintage amps but seldom are now due to the economics of amp building (a cost issue, not a tonal one!). Chokes extend the life of the power transformer and rectifier. A choke is much more than a simple inductor. It can also store energy like a capacitor. Better voltage regulation results from using a choke that puts less stress on your power transformer help it to live longer. Chokes permit higher load currents to be drawn from vacuum tube rectifiers without exceeding their peak current rating. This means life extension for your tube rectifier! Solid state rectifiers run happier as well. If that's not enough, the tone of your amp will noticeably improve with a "peaked and tweaked" hand-tuned choke from Mercury.

CAUTION! The voltages in your amplifier can be dangerous. Transformers and chokes are not user serviceable parts. Installation of these components should always be performed by an experienced technician. The simple ability to use a soldering iron is not enough to qualify a "do it yourself person." Those who are inexperienced in working with electronic circuits should never attempt to service their amplifier. Household line currents can be deadly!! Transformers, chokes and large filter capacitors can store a dangerous charge for several days or more after the amplifier has been unplugged. Never touch the terminals of such devices without being certain of their charge status. Risk of shock and damage to equipment may result from mishandling and/or improper use of these components. Please use common sense and always think safety first. After all, tone is most enjoyed when you are alive to hear it.
