Circuit differences K200 and K250 heads? [message #27980]

I've never had a K250 head.

I currently have a K200, which has been re-capped, and the PS caps etc upgraded.
Through the 70's, I played a K400 into a pair of 3x15 CTS cabs. That's basically two K200's with a common power supply.
So, my knowledge base is almost exclusively the K200 designs.

Lately I've been considering a K250 head. Of course it would get a full re-cap, and similar PS upgrades to what I've done to my K200.

What I'm wondering is, what were the circuit improvements done to bump the power up from around 100 watts RMS into 4 ohms, to 125 watts into 4 ohms on the K250? Heavier power transformer? Stronger output devices? More of them? Higher PA voltages? I think the K250 was rated to drive 3 ohms...is that where the extra power came from?

My K200 now clips at about 115 watts into my 4 ohm bench load. It's a really strong amp. Will I really get much more from a K250 into the same 4 ohm cab?

Thanks,
Dave O.
