Hi All,
Nice radio Ron. A fine catch! At the end of July I picked up a Philco 90 for $65.00. A lot was wrong upon inspection. The (tiger stripe)? veneer is mostly gone but the rest is o.k. The primary on the first detector coil was open. The speaker field coil was open also. The filter choke along with the output transformer were open too. The tunning cap had to be cleaned also.The choke and output transformer were ordered from Radio Daze along with a #47 tube. The detector coil break was on the first loop. The speaker field I wound with #36 guage wire. I only had a little over a half pound which gave me 2600 ohms so I put a 10W 500 ohm resistor in series. You talk about tough getting the speaker core out! Wow. I drilled and tapped a 1/4 bolt to hold it in. After a rebuild of the cap blocks, a few resistors and electrolytics it plays great!!
Last friday the wife and I went back to the same place and there sat another 90! I got this one for $43.00. It rained here all day Saturday so I tore into this one. Not much wrong but a lot of recapping and resistors. hopefully I can power up tomorrow. The chassis has a lot of rust though. Will have to start cleaning after I get it playing.
