Concepts 2 315 fan mod and cable change



July 2018


After some use of my “new” 2M amplifier I decide to change the power cable and put a fan on it. First, I was thinking to just change the cable, but, I don’t like the old power connection, so I decide to solder the cable directly.

This is how the amplifier look like inside.


I don’t want to run the fan at full speed, so I put a 70 ohm resistor on it, and a fuse of course.


Here is the new power cables and the out going power to the fan.


How to attache the fan? Well.. one idea is this. Working very well!


All put together.
