David,

I have experienced a problem with a failed power output device that allegedly was due to improper torquing of the device to the heat sink. Palstar replaced the failed power device for free and reworked the unit, and I think I paid return shipping or something like that (about $25). In any event, it was a very fair arrangement. If the unit you are looking at works now, and it is from 2019, the chances are it is in good shape. For me, it has been a "go" or "no go" type of device; there is no grey operational zone.

The plus side is that Paul, the president of Palstar, and the staff there are great albeit a little overworked. I highly recommend the amplifier. I have other of their products, and, as a formed RF design engineer, I can tell you that their products are well done. As far as service is concerned, you know the old saw, you can have it done well, done fast, or done cheap, but your can only pick two of the three options. My service has been done well and at a fair price, so if you need service, prepared to be patient. In my experience, it took twice as long as I expected to get the unit back (6-8 weeks), but it was worth it.

Good luck,
