I'll give the picture attachment a try. The wiring on this chassis looks original and factory. The no. 1 pins on all of the tube sockets are grounded
with exception of the rectifier tube which would indicate to me that it was a metal tube set from the beginning. If it was retubed and modified
later, it was a professional job and I would say completely rewired. The output tubes are wired in pushpull and are along the left side of the
chassis. The audio driver transformer is located on the bottom of the chassis. The IF transformers were made by JW Miller, another possible
indication that it was rewired at sometime. It had 8 tubes originally, some were missing. The set included a 5U4 Rectifier, 6K8 Mixer, 6SK7
RF Amp?, 6SG7 IF?, and a 6SR7 det/amp. Looks like the output tubes were 6F6s. Thanks for reading my post.
