--Basic Electronics--by Van Valkenburgh,nooger and neville-out of print can be found on that auction site- there is a cd and softcopies can be found although a little pricey--these books were i believe precedessors to the navy electronics books-these books are very good at explaining tubes, power supplies,rectifier tubes ,choke and rc filters -no theory no math except ohms law---although somewhat basic and remedial--the best i have come across for the beginner- really gives one a good background on just what is going on in there-some things are outdated ie: condenser for capacitor-volumes one and two are the most pertinent-
also if one google's --boozhoundlabs-- a vacuum tube hifi primer--he also explains quite well who is doing what and why
