Over the week end I picked up one of those sky scrapper art deco classics-a 41-290- at an estate sale. I pulled the chassis out when I got home and cleaned it up and made sure the wiring was ok etc. It needed a glass dial and I replaced it with a scale from an old 41-280 set I had left over. I turned on the set, and to make a long story short I have two questions
If you are looking at the dial scale on the right hand side where the "Broadcast", "Standard" and "Short Wave" bands are noted, there is a lone pilot lamp in a housing that appears to be on a pulley system floating tied in to the actual pointer pulley sytem. This is different than the 280 where there are 3 seperate housings for the lamps. In any event, how do I wire the floating housing so it works correctly when changing the bands?
Second, the radio does in fact play and I can pick up a lot of stations. There is a louder than normal hum coming through. Do I have a condenser/filter problem or just a bad tube? I am waiting for my test equipment to arrive this week end (tube tester, signal generator and volt meter). Where should I start?
Thanks for alll your help in advance.
