Reviews Summary for Ameritron Step-Start Inrush Current Protector ICP-240
Ameritron Step-Start Inrush Current Protector ICP-240 Reviews: 11 Average rating: 3.8/5 MSRP: $79
Description: Ameritron's Step-Start Inrush Current Protector stops damaging inrush current. By starting your linear amplifier through a high power current limiting resistor and then shorting the resistor with a relay, you get a start up sequence that's easy on your tube and power supply components.

Now you can add this protection to your amplifier without complicated wiring -- you don't even have to take the cover off. Simply plug your amplifier power cord into the Ameritron Inrush Current Protector. By limiting heavy inrush current to safe low level, you'll get a longer lasting amplifier. You might avoid replacing expensive tubes and components. Avoiding just one repair job could pay for this extended protection.

Momentary high-voltage "spikes" in the ac line can also cause damage to your amplifier. The Ameritron Inrush Current Protectors have built-in varistors to absorb these spikes before they can cause damage. Works with nearly all linear amplifiers. The Ameritron ICP-240 is for 240 volt wired amplifiers. Limits current to 12 amperes during heavy draw inrush period. 20 amperes continuous operating current.
Product is in production.

A must for Linear Amps  Time owned: 0 to 3 months
I bought one of these ICP-240 which is an inrush protector, to limit the high current when first switching on a Linear Amplifier. I bought it to protect my ON/OFF switches from the high inrush current. My first ICP-240 was defective and the realy was not inplace and it immediately burned up at the very instant I turned it on. I sent it back and got another replacement. So far it works well, but I will write more after I have owned for a while. It seems to be well built, I only question MFJ's quality control. It seems to be hit or miss. The design is the same used in the Ameritron Al-1500. It is a well designed unit. It will save those ON/OFF switches on older amps like Drake L-4b, which are not available at all. It will also save wear and tear on other amps power supplies.
I gave it a 4 instead of a 5 because of Qaulity control issues at MFJ. If you get one, open it up and ensure the relay is seated and working freely. The spring can fall off and the relay will not close and cause the 20ohm resistor to burn up.
