[Amps] Interested in re-purposing a Dentron Clipperton-V - question about possible power power transformer ICAS KVA

[wb0gaz at yahoo.com]

 I've got a Dentron Clipperton V (2M 500W single 4CX250) amplifier, purchased used some years back (when shipping was cheaper!).

It looks like it's in clean but not pristine condition.

I've never used it, and my fixed-station circumstances somewhat discourage tube QRO on VHF.

>From everything I've read (and just looking inside at the "RF Deck" design), I'm inclined to agree with commentary that it's not a very effective RF design for 2M (lumped output tank elements, open frame T/R relay, etc., as if it was designed by someone that hadn't looked at VHF amplifier designs of the same era.)

So, I'm interested in whether the amplifier (cabinet, metering, power supply, cooling path, etc.) could be re-purposed, by cleaning up the power supply (replace components in the HV rectifier/voltage doubler circuit) and replacing the "RF Deck" (but with what, not decided.)

About the power transformer - what is done with this in terms of a project is dependent on the power transformer (assuming it's not dead, which I'd verify) capability as much as anything else.

In the spirit of "look before leap", I'm eyeballing the power transformer (which in the manual is just "power transformer" with no other spec.) It has two primary windings (so 115/230V primary), a HV secondary winding that uses a voltage doubler to generate the (claimed) 2250V plate voltage, and several auxiliary windings (filament, 12V control, negative V for grid bias, positive V for screen voltage.)

The transformer's core dimensions (excluding the windings) are 3-1/2" x 5-1/4" x 4-1/4".

By comparison, my Dentron GLA-1000B's power transformer (same, excluding the windings) are 3" x 3-1/4" x 4". 

Comparing the cubic inch volume of the two transformer cores yields that the Clipperton-V is about 1.8 times that of the GLA-1000B's power transformer (whose only duty other than HV appears to be four sweep tube 6.3V filaments, so it has a bit more work to do there.)

Given that a GLA-1000B can deliver 500-600 watts (including whatever drive power passes through, maybe 75-100 watts), would comparing core volume (above) be a reasonable way to estimate the power transformer power thru capability?

Thanks for any comments, observations, or (if you're in Colorado) a plea to rescue the amplifier!
