Hello! I'm Mike. I have been interested in vacuum tube based electronics for awhile, and been lurking these forums for a few months. I just recently snagged a Motorola console radio and Panasonic portable B&W tv set. I also recently got a Sencore Super Mack CRT tester from a local surplus electronics store, and it seems to be in non working condition. I would love to get it working to test future acquisitions, and that is what brings me here today! So, I figured I should write a little introduction post before asking y'all for help
