I just ran across and purchased a vey nice condition Philco 531 in a consignment shop and it seems to be intact with the exception of needing a new grille cloth and a cabinet back (assuming it was made with one). I haven't removed the chassis from the mounting board and checked any components underneath as of yet, but since it looked in such decent shape I decided to hookup the unit to a variac and slowly bring it up to voltage. All the tubes have good filaments (and to my surprise the dial light works) but I hear nothing at all (even AC hum) from the cabinet speaker. As it was about 1AM, I didn't go any further.
Just wondered if any of you had any tips on this unit you could share - I'd appreciate it. I did run across an article about replacing the speaker using a PM type and audio transformer if the speaker was bad. Didn't check the coil last night but I did see "Utah" on the speaker itself if that gives a clue about some of the faulty units. Thanks in advance!
