Honestly I wouldn't know the difference between an old school well built to a newly produced one that's a piece of junk. I don't have a mobile setup and never believed in running a mobile amplifier in a base situation. I know many do and am sure there's nothing wrong with it. It's just my preference. My op was purely based on my curiosity of the "Dave Made" amps being advertised as such. Back as a kid (1977) I heard the Dave Made name and the quality build they were known for. Being I was in Brooklyn NY and the DV's were made in NJ I'm assuming many who owned them simply took the ride over to the Jersey side in order to business with Dave himself. I don't know when the real Dave stopped making amps but if I'm correct he was still around building certain products within the last ten years or so. I say this because those who were lucky enough own those transceivers/transmitters he built have an idea when he stopped making anything himself. 73
