Bill & Texas,
Thanks for the hint's and help, I really appreciate it!
Instead of just using a freq. gen. (the building that I was originally testing the radio in is unable to receive any real signals) I brought the radio back home and hooked it up to my newly acquired power supply and connected an antenna like you had said and was able to pull in stations from 1500 KHz down to 800 KHz loud and clear but still nothing lower.
Just to verify that I wasn't crazy and just hearing things (or in this case not hearing things!!) I used my freq. gen. to verify my operating range and it is still 800 KHz and up.
I do have a schematic coutesy of Nostalgia Air (I love that site!) and will go back through the radio to verify that the re-cap job was done correctly
and it is 100% correct electronically.
I don't have any extra tubes laying around. I would love to have a spare set to swap in and out to see if that is the problem.
I will more than likely go the Solid State route on the vibrator and forego messing around with the old one seeing as how it's a single point of failure.
I will also check the coils and if worse comes to worse, get them re-wound to ensure that it will never be a problem.
