70 speaker
#1

Hello, this is my 1st post in this phorum. I bought a Philco model 70 from Ebay that was in good condition and mostly original. The problem is they didnt remove and pack the speaker (which I had requested), and it came loose and busted the grill. I had the cabinet repaired, and it looks really nice. I havent powered up the radio yet to check things - the seller said it had a low hum and static. The speaker voice coil rubs the magnet when I press the cone. It has the screw in the middle. Before I send this off for a repair, is there some kind of adjustment to center the coil? I havent had any success in searches here on this, and havent found anything on youtube (although there are some interesting videos on rebuilding some of these radios).

A little about myself: I am a 'retired' electronics technician from a large company from about 12 years ago. I had studied (from reading a bunch of my uncles McGraw Hill books), have knowledge and worked with tube electronics from a very young age, which is, and always has been a love of mine. I graduated from a technical college and worked as an in home/shop electronics technician with about 17years in the profession. I gave it up right after 911, and the introduction of plazma and LCD tv's. I caught the very tail end of tube sets that came in for repair in the mid 1980's. I am not retired from the company, but no longer work on electronics for them.

I have the electronics knowledge, but lack experiance on early equipment, such as this Philco 70. Any help or links would be appreciated as I work to restore this radio. Also, I am trying to find the post/thread about products that remove rust from metal. I read it a month or so ago, and now cant find it.

Thanks,

Tim
