Hallicrafters S53-A
#1

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.
