I had a hard time removing the speaker from the cabinet. Of course, two of the three speaker mounting nuts were rusted to the decorative speaker screws.

Fortunately, a little PB Blaster and some gentle persuasion soon took care of that problem.

I connected the speaker, connected my little 12 foot antenna, plugged the T7-5 into my Variac, slowly brought it up and...

It's Alive!

Less than three weeks...not bad after the last project.

Of course it isn't finished yet. There is still the matter of the dial pointer, and replacing the dial scale. In addition, the speaker sounds awful - much like a Philco 20. There is a good reason for that...

Look, Ma, no spider! And so the voice coil is rubbing the pole piece like crazy. The cone is not in very good shape, either. Looks like this calls for a recone job.

Well, this weekend I'll see what I can do about the dial pointer, in between my other weekend projects. I'm just happy to have this one basically done! Icon_biggrin
