OK, thanks for that little tip, I'll give that a shot.

Also another thing I noticed is that this TV has an RCA Jack on the back in place of the 300 Ohm screw terminals for the antenna and then from that there was a 300 Ohm twin-lead that was hanging off the back, I was wondering how the original Antenna terminals would of looked like on this TV so I could maybe try and get it put back right again.

And then I was testing some of the tubes in this TV and I noticed that one of the 5U4G Rectifier tubes measured shorted in both sections, would that happen to have anything to do with the "bad 5v Transformer winding" issue? The other 5U4G tube was fine by the way and it measured into the 90s emissions wise.
