SB 200 makes a great Driver

Just something else to keep in mind with tube 'specs'. They are not the minimums, but are the maximums for good performance characteristics. They are representative of what the manufacturer feels is the 'best' results for that particular tube's normal usage. Those 'specs' can be 'pushed' a little with no huge harm done. The key word in that is 'little'. If those 'specs' are exceeded, you just blew the warranty, and that ought to tell you something. Not telling you anything new, am I. Just handy to remember...

No warrenty on free tube. HI Hi Here are the specs

Is there anything you need to do to the SB-200 to work on 11 meters AM.

I thought the SB-200 needed 100watts drive? I'm going to use the one I just got for the ham bands, but would also like to use it on 11 meters being driven by my Golden Eagle MKIV if possible.

If it works like you said 30dk to 200 PEP: It would replace the Contex 6706 tube amp I use for 11 meter now.

100 watts pep max. You can run with less. You can use it with the browning but need to use a keyer.

60% Peak input power for peak output to the antenna power is a reasonable figure for a class B H.F. power amplifier.

2500 Watts input should yield the magic 1500 watt P.E.P. figure. If not then maybe it's not loaded properly, voltages are sagging like an old Mae West or peak emission is down.

I have an LK-2000 on the air. It meets this figure with a 3-1000. I also have a GS-35B and am waiting to convert. I'm also waiting for a little heavier plate iron that will fit in the pedistal.

Converting the BTI LK-2000 to the GS-35B - N9ADG

He converted his LK-2000, might be helpfull.

Thanks. That was interesting.

I'm planning on using orange turbocharger hose for a chimney.

Done it before with other ceramic tOObs.

Winter project....

You won't be able to watch your tube glow. I am using a Coelman lantern globe.

Yeah you are right. I'm over watching tOOBs glow though.

If I want to see that funky ceramic glow I can just open one of the transmitter cabinets at work and peek at the IOT running 36kv.
