Well, Did some checking tonite and it looks like a couple 10uf electrolitics were added under the chassis, but they never disconnected the old caps in the cans. All wires are still tied to the lugs and the cans show no signs of being opened.
Caps were added downstream.
Have never seen this before.
Just to verify, I removed the tabs from the lugs with all wires still attached and powered it up.
Powered up fine, so I checked a few tubes for voltages.
The 24's are supposed to have 250v. Two of the were around 240v and the 3rd one was only checking about 5 volts.
Apparently something is choking off the power to that 24 tube.
Have no sound other than some crackling and a slight hum coming from the speaker.
If I tune across the dial with another radio playing, I can get some interference type noise from the other radio at a certain frequency.
ANy suggestions from the Philco experts?
