Premium Rectifier Board

$15.00

Many typical rectifier boards/circuits use only cheap 1N4007 diodes. Our Premium Rectifier board includes a whole lot more!

UF4007 diodes provide much faster switching time. The 470K resistors keep the diodes balanced preventing a mismatch which could lead to diode failure. The .01uF@1000V capacitors help protect the diodes from the voltage spikes which can occur as the amp is switched on and off.

Easy to install in any amp that uses a fullwave rectifier for B+. Includes installation diagram. Can also replace, be switched to, or run parallel (diode steering) to a tube rectifier.

NOTE: Not applicable for amps that use a bridge rectifier in a voltage doubling configuration, e.g. Marshall JMP100.

DISCLAIMER: User assumes all risks. Performing these modifications will most likely void the warranty on your amplifier. Working on amps can be deadly if you do not take proper precautions. Read and follow the diagram or instructions very carefully. Basic soldering skills and basic user-supplied tools are required. If you are at all unsure of your ability to perform these modifications STOP and take your amp to a professional to be modified. You can also send your amp to us for modification. Contact us for pricing.

DIFFICULTY LEVEL: INTERMEDIATE [Follow safety guidelines for working with electricity. Basic soldering skills and knowledge of working with AC/DC circuits. Identify all terminals of electronic components using data sheets. Read resistor color codes and capacitor values. Measure and connect high and low voltage AC and DC. Understand basic working of vacuum tubes. Use all functions of a multimeter. Understand Ohms law and apply to basic circuits. Work with basic hand and power tools.]
