I really appreciate you all's help. I pulled the resistor and got about 8 watts right off. Then I was looking at the output network which you see I'm using a T network and something didn't look right so I changed it and I'm at 15 to 20 watts. One you get here they start popping up exponentially but that resistor was holding me back. You guys were right on. I wonder is those two 33 ohms resistors are killing my base current? It's so hard to adjust with only 10 ohms because one each transistor turns on the load changes on the LM317's. I'm slowly bumping up the driver's biasing too. I'm sorta concerned with heat so might run it shy of full 200. The broadband characteristics are pretty good. Through a frequency span of 2.5MHz under PLL control it jumps 15 to 20 watts right now. Probably the output network.
