I am waiting for the new drivers and new finals for my transceiver to arrive (should have been here already). One thing has just cropped up and perhaps some of the more up-to-date knowledgeable ones

The mica washers can probably be split to make them thinner. They require thermal grease on both faces. Thinly applied. The silicone pads don't crack like mica, don't have conductive inclusions like
