Commando,
If you have the schematic with p/n's for the fet box I'd appreciate a copy? I'm competent with a solder station but am not a component level design engineer. Dave 148
Is anyone running one of these amplifiers and how reliable is it; Can anyone point me to a seller as I cannot find anything on Facebook or Google? Unit 148
Thanks guys,
Marconi, I was in touch with Lee a couple of exchanges of messages but comm's broke down even though I could suggested after my funds clear I can arrange courier pickup.
I'm inclined to think that either 50V LDMOS or a tube is the way to go and not 12V or volting them higher that 14 for long term reliability and reasonable IMD numbers. Nomad, there is a faily big difference between average and peak power draw and with a brace of decent AGM or Lithiums and a...
Thanks for all the feedback. It is interesting to reach that power level in a mobile daily driver rather than just made for shootouts. Out of interest who other than Dahl produced transformers for tube mobiles? Unit 148
OK on those 65V LDMOS. You say there are 4 device bare boards available - with a schematic or and parts list? I have only seen single and dual 65V LDMOS builds out there from RF Man: https://www.youtube.com/channel/UC7r5QeuynhXudskQDl7J45w/videos and...
Thanks for your thoughts. Regarding drive. Yes, that is an issue. I do wonder how much drive one would need in a non-competition amp for a tube like the 3CX3000 which I believe is fairly popular at this power level? My only concern with a solid-state amplifier that can run this power reliably...
I currently run an old 8 x Toshiba 2879 mobile amplifier which will be shortly going to a new home.
I would like to step up to the next level in mobile power. Mobile power supply is not a problem as can add alternators and or batteries as required.
I operate mainly on sideband so will use an...
Thanks TM. I had found the CBT site schematics but they only have the base amp's and a mobile I have has been butchered around the inverter so those schematics are no great help. Unit 148
