D17 is about 1K ohms both directions, D18 about 2K ohms both directions. I can order these 1N5711s on eBay but it will take a couple weeks at least to receive them here in CR. Will have to re-assemble the radio to test CAL TPA settings, forgot to do it first.  PAs don't show any physical signs of cooking. I'd set the radio for 40W max on SSB and backed off the audio level so that the wattmeter showed half that. The 100W on the wattmeter was only measured in CW mode.
