Not legally, at least in the U.S.A.  11 Meter equipment must be type-approved, and that includes being within the power limits specified by the FCC.

"this amp,can it be converted to operate on 11 meter? "

Sure.


"if so how so "

Without a tremendous amount of difficulty.

But, since your are a duly licensed ham radio operator, you've studied radio theory and learned quite a bit, which you've proven by passing tests.   You should already know about inductors, capacitors, tuned circuits, impedance, reactance, Pi-L circuits, tank circuits, etc.
You do, don't you?   Of course you do - you had to learn all about them to pass your test, didn't you?

Perhaps you are like me, and a bit rusty.   Maybe it would be a good idea for you to do what I do - go refresh myself with some of my old books when I am about to get into something.

But, for some reason, the way you asked, it makes you seem clueless about it.   Since you must have some knowledge about these things, here is a suggestion for you:  Don't ask a vague, general question next time.  Ask a specific one.


Next, I am curious as to why anyone would want to do it?
First, 11 meters is the Clown Band.  While it would not be illegal to own such an amplifier, it would be illegal to use it on the Clown Band.
Further, that amplfier requires 80 to 100W of drive I seem to recall. Whatever would you drive it with?   The typical Clown Band radio has an output more like 3W.  Next, how would you key it?  The typical Clown Band tranceivers have no means for keying an external amplifier.

You certainly cannot desire to operate it on the Clown Band, as that would be prima facie evidence that you are a Clown operator.

So I'm wondering why you would want to take a fine piece of classic ham radio equipment, and turn it into a big paper weight? - as that is all it would be good for after it is butchered.

Good lord, i thought i had heard and seen it all now this comes up. Typicial example of a chickenbander with a ham license. This is what our future holds for the rest of us. Most of these guys only want to get a ham license so they can brag to their other cb buddies about being a ham.
