Got this free a week ago.
Will be a christmas gift to my youngest boy but.........
owner said he messed up the speaker wires,, i fixed that and went over it some. Its all original except tubes.
this is an 8 tube radio by the way. it looked so nice and nothing to worry about under the hood i opt'd not to recap or anything. it looks like its been mostly just stored and such, with some minor exterior scratches and such.
powered up and it worked fine. Since i disagreed with the design, I took the set out of the cabinet and did a mod. I cut the bottom open and made a non-conductive plexi-gllass cover to go on to make it easier for future repairs plus its really neat to see all the parts.
I did notice during my power up over a few days that the radio acted like there was an intermittant connection but it seemded to go away on its own. the speaker would sorta cut out or pop.
I installed the radio chassis into the cabinet and powered up tonight. The left 75% of am band was absent but slowely all AM band was absent,, all gone with some slight noise from the speaker.
I dont have a scan of the schematic, just a pdf.
I have no more radio channels anywhere coming out. If i let it cool down some i can revive the sound some but eventually the speaker for a few moments goes to high crackly tone then goes almost dead, i turn up the volume an i can hear some noise but not stations.
Is this a symptom of a bad audio output xfrmr? i need to act fiast to make the set work by christmas.,, shipping and all considered.
thank you,
Scott
304 772 3411 if anyone wants to talk through probable faults.
I plan to take some measurements tomorrow. I hooked my meter up to the two wires that connect to the speaker (speaker disconnected) and i was getting zero ohhms.
the speaker reads about 2.3 ohms itself.
