    palomar 250ld or 450ld ?

    If it is a mosfet amp, chances are it is linear. That is one good thing about moving away from the BJTs (bipolar transistors). With the MOSFET design it is easier for them to just make it operate at least somewhat linear. I have seen the older Palomar amplifiers that were stamped AB1 (which...

    Kenrich Eagle 500

    Yes, you can. however, the "20" in 20LF6 refers to the filament voltage. The 26 volt filaments will be operating below rated voltage and it depends on if they are wired in parallel or series as well, if series there could be a significant difference in the voltage they are getting. Which means...

    I would recommend the 2970dxn2 personally. They just work and have circuit improvements that have been implemented over the years.

Ok, in all seriousness, probably any base station which is a mobile radio in a big metal box with a weak power supply (I cut out most ranger/galaxy bases) . The AR-3500 not so much for the finished project, but it was full of...

    2950 not working

    Check the rig for the KIA7310P ICs, if present, order up some TDA7310P. For some reason they go bad or get flaky over time. And yes, I know it doesn't make sense theoretically that they would, but THEY DO. Replace the KIA's with the TDA's and then check both VCOs to make sure that the reference...

    if you had to choose...

    I'm with Moleculo on the 757, but CHECK IT FIRST. See if its something simple like others have mentioned, the switch on the back. Maybe put it in TX mode and tap on it a bit to check for a loose connection or solder joint, easy fixes. I am not sure what is within the scope of your repair...
