New to 6 meters and trying to assemble a 6 meter station. I have been casually looking for a "donor" amp to ship to Lou for one of his conversions to 6. In my research and thinking the situation through it has dawned on me that both of my "driver" transceivers (and Icom 551 and Icom 575) only put out about 10 watts. I'm was looking for a Heath 220-221, an Amp supply LK 450 or an Ameritron AL80A to have the conversion done to but with only 10 watts out of my exciter what kind of output would I get out of a converted tube amp. Or would I be better off picking up a TE Systems brick? Thanks, Mike....

Figure on about 12db of gain give or take. 10 watts in and 160 out.

Thanks, that's about what I was figuring on concerning output for the 3-500Z's. I think I'll stick with a brick until other things develop. Thanks again, Mike....

several of my customers use bricks in the 100w range to drive the converted sb-220.  It is not the norm but it does work.

Well, that's something else I have considered. Solid state transceiver, solid state "step up" and finally one of those fine amp conversions out. Now that is something that would probably fit in. And an avenue I would like to explore more.Thanks. Mike....

A grid driven amp can give you the legal limit with just a few watts drive.  Whether or not you can find somebody to build one is nother matter.  But wait Lou just posted...............

I have a single-tube 6 meter amp that runs about 1200W output power with about 10W drive.  20W pushes it above legal limit pretty easily.

If you're interested, it's not a difficult project although it certainly is heavy. Wink

Nice amp.  I enjoyed reading through all the pages of that 73 magazine.  I also built many GG amps using the 4-1000A (and multiples there of   Grin ) in the 1970's.  I sold all of them but every one is still running.  If you ever got a good 4-1000A and did not abuse it, it would run almost forever.

The amp in that article is still on the air today  and used a surplus "pull" tube in 1984.  Same tube still produces 1500W output, today.  The tube cost me $100 in 1984. Wink

It's not shipping yet, and it requires 100W drive power (for rated output).

A tooob will do it with a lot less drive power and probably lower cost. Wink
