We are selling Palomar MAX-MOD Transistor upgrade For High Power CB Radios Does the regulator in your radio run hot? Excessive heat from a transistor means the part is undersized for the circuit or that the circuit itself is not very efficient. Changing the radio’s modulation circuit is impossible. But the solution for this problem is the Palomar MAX-MOD Transistor. Palomar is a famous old CB brand name from the USA. The name is owned and used now by EKL Components, the mother company also for Magnum Radio’s and RF Limited Accesories. New in the Palomar program is the MAX-MOD, a special PNP transistor. The MAX-MOD is a replacement and upgrade PNP transistor for the modulation circuit in most radio’s. The MAX-MOD replaces the common 2SB and TIP parts. The MAX-MOD works very well in 10M radio’s, including Stryker, Anytone, Galaxy and President models. The MAX-MOD will give the RF section the current it needs and will increase the peak power by and average of 10% or more. The MAX-MOD has the same lead spacing as the smaller transistors it replaces, making soldering very easy. The MAX-MOD uses a huge TO-3PL package for improved heat dissipation.
