In my base i allways run a bit higher voltage ab. 15 to 17v so i get more output same input.

My B300p in mobile runs quite hot at full output but it have worked 10 years without any problems.

What power do you put into the mobile amp pienari ? cheers.

When running a 6 stage amp I always used a low pass filter connected straight onto the amp with a double 259 connector on the rx side,stops the reflective power.
