Galaxy DX-959 Mosfet version mods

You dont need to replace the AM regulator if you "volt" the final. That will give you more power on AM and make the radio run cooler on SSB

Volting the final is never a good idea. How will that make it run cooler on SSB? I think if you would ask say DTB if he does that he will say NO.
 
On SSB 12 volt goes through the AM regulator to power the driver and final.

On AM only 6 (ish) volts goes to the driver and final.

You move the final to a 12 volt source you get more power on AM and since the current to power the final is not going through the AM regulator the AM regulator will run cooler without needing the upgrade that DTB recommends.

So why is volting the final never a good idea?
 
Over the years volting finals has always been a bad way to tune a radio. I know mosfets seem to handle voltage better then the old 1969 finals. I still don't think that's a good thing to do, maybe things are different with these new mosfet radio's.

Do you even know what your talking about? On AM there is only 6 volts going to the final, on SSB there is 12 volts. When your volt the final your just giving it 12 volts on AM as it would run on SSB. How is that bad? Is 12 volts to much for a 1969?

    I will not be there but hopefully by the end of this month I will have my New tower and antennas back in the air including my M2 6M5X. The old tower and all of my antennas came down in October 2023 during a Hurricane.
