Not really good at alignment until I get a station coming thru...and finally one came thru and I was able to adjust the trimmers and voila it came alive across the dial. I get a little static between stations but station come in strong! Volume control doesn't work real well...but actually good enough ...It must short out except at the very loudest with miniscule adjustment that is....good enough. I guess I could try to open it up and clean the control. Thanks to all for help and support!

A couple of things... You won't be able the best of performance until till the IF is peaked up on frequency (470kc). Can't fudge it by peaking all the trimmers for max signal on the BC band!!! No no no!
Volume control won't work properly without a good ground connected to the chassis. The set needs a good earth ground to work against the antenna through the volume control.
