Hi Phil,

Glad that I was able to help! How does the radio sound? The '42 is a pretty solid Audio Output tube, so, if the speaker and the rest of the radio are good, the 71 should sound nice. The speaker is a big improvement over the earlier Model 20 "Pie Plate" Speakers. If you put in an Aux Input and feed an MP3 Player or an iPod / iPad into it, you will be amazed. (Also a good way to play period appropriate program material (Big Band / Swing Music WWII News bulletins, Roosevelt Fireside Chats, etc. through the radio). The only other major bugaboos on this radio are the "Autodyne" 1st Detector (Converter) and the dreaded cellulose insulators causing corrosion and an "open circuit" on the primaries of the RF Coils and the "Tickler" of the "Oscillator" Coil. Much about these in this Forum, most courtesy of Ron Ramirez, the Professor (Pro-Ph-essor?) of all things Philco!
