Raliegh, it sounds like your on the right track. Since its a sudden shift, not a drift, I would think it's mechanical and may also be heat related since it resolves itself if radio of for a while. The only other thing I can think of is a tube shorting/opening when it heats up. Try substituting tubes in RF curcuit and replacing grommets. PL
