You're right exray,, its 440 ohms on the schematic.. The 140 ohms was a typo. I've since corrected it.
My meter is fine, tried on a VTVM too.. 49 or 50 ohms. This radio uses a 3Q5GT tube. The voice coil measures 3.3 ohms.
Maybe someone put in a speaker and transformer that didn't match..I dont know..
I know this is a cheap radio, but the case is perfect, so I don't mind if I spend a few bucks to get it to play at its best. Any ideas on where to get a speaker and transformer set, or maybe just output transformer..
Dont know what to do...any suggestions?
