Well at 13.5 pounds they are not power houses that is for sure. I do plan on occasional prob. once every few years going on AM. I do prefer SSB so that is where I would more then likely spend 98% of my time.

I do not need to hit my target of 2500V @ .800ma that would be if I wanted to get every last watt out of those tubes and I do not need to do that. I did not know which way would be considered more durable wiring them series or paralleled. I normally go for durability and cool running for electronics. So I was guessing that going for current and letting the doubler do it's thing for voltage would give me more head room and cooler operating. Since I have no practical experince in this area I figured I would ask.

I am going to be powering 2 GI7BT tubes. They are rated at 350Watts each but most home brew guys are getting 500watts each clean on the scope for a total of 1000watts at 2500V @ .800 their is actually one guy getting 1200 at that power level. I think that was with 60 watts of drive. Most of the other ones I have seen they stopped at about 48 watts of drive.

I have no desire or need to try to get all the power I can from them. My target is 600watts clean in all modes if I can get more then that fine but my goal for my first amp built from scratch is just 600watts. Like I said before I am not looking to get crazy and push the tubes to their limits if I need more power I can get bigger tubes!

So if I am getting this right consensus is on wiring them 2200V at 1amp and not bothering with doubler at all just simple full wave rectifier. So a .200ma buffer from desired peak current of .800 is considered enough head room for long service life? My goal is to run those transformer's cool enough to not tax them too much.
