Just the one item -- it seems the late Howard S. Pyle, W7OE, wrote Troubleshooting Amateur Radio Equipment, published by the not late company founded by and named for Howard W. Sams. It's out of print and my first tries at the Usual Sources have turned up nothing. It looks to me as if it would be a very handy book for any ham who likes older radio gear -- but anything Mr. Pyle wrote is worth reading.
Every so often, something he built shows up at the Dayton Hamvention. Yes, you could tell, even without his callsign on the front or back panel. (It usually is) His construction style is distinctive, with well thought-out layouts, neat wiring and sharp, concise photometal labels on everything. His writing is a bit that way too, carefully engineered and logical, though friendly in tone.
His is a name and callsign to watch for at hamfests and used-book stores.
