Power supply rectifier diodes might get a bit warm, but not excessively hot. These amps did sound good, little question to that. They were also built a little less as Saturday night specials than many, so they get some respect. Again, not ham level amps but they fill the outlaw CB’er bill which was Palomar's intent at their price level.
I think I have most of the garbage filtered out of the 90A’s transmissions, at least I haven’t heard the neighbors complaining about it. In knowing the distortion was there I think a bit of prevention went a long way before really using it. (Of course if you live in a remote area with no neighbors, this won't be an issue.) DX was booming for a little while especially on 6 and 28 last night, and I was getting some good signal copy far away so yeah, these amps work!
