I had one of those, also!  Did yours have the after market TVI kit 
with the perforated sheets that enclosed the entire rig and had about 
a thousand little screws that held it together?  i bought mine used 
from Allied Radio in Chicago.  Got it home and it had a burned out 
4D32, about a $40 tube then.  Big bucks to a teenager!!  Allied 
replaced it for freee!!  My first grown up rig after the Globe Scout 
40 and the Harvey Wells TBS50D!  Why can I remember all that stuff 
and forget what I am supposed to do after lunch!
