Telebar Power up

Well, replaced the one two section candohm resistor with a terminal strip and two ohmite wire wound resistors.

Hooked everything up, hooked up an antenna, turned the tuner to channel 7 and fired up my modulator. Brought the set up slowly on a variac. At 90 volts - no smoke, no bad smells, all tubes lit. Cranked it up from there slowly and CRT lit up and heard very low static - then very low sound. Waited a few moments looking for smoke or any sign that the set needed to be shut down. All ok so far.

Walked around the front of the set and saw a decent picture. Switched signal over to my DVD player (thru my modulator) for a test pattern. With only a slight height and linearity adjustment, then an ion trap adjustment got a decent picture. Sound was very bad. Barely audible and full of static. Fine tuning did nothing. So I switched to channel 8 and got fantastic sound. GREAT, just need to adjust the channel 7 tuning lug, right? Wrong! When I removed the channel/fine tuning knob, the tuning screw for channel 7 was either sheared off or not there. Then as I turned the tuner around - noticed the same thing for channels 3-10. No tuning screws visible where they should be. Well since the set had a decent pic, I decided to turn on the radio. Turned it on and CRT slowly faded to black and TV sound faded as well. Nothing from radio. Hmmmm??? With the radio still on, I turned off the TV power knob and the radio came to life. Dial lights came on and got stations on AM and FM bands. Now it gets strange. Turned off radio knob and tv knob and the set would not turn off. Had to unplug it totally to kill the power. So something is not right there. Good news, nothing blew up and got a raster/picture and sound. NOW THE BAD NEWS!

Pulled the chassis and pulled out the turret tuner. EVERY SINGLE tuning screw from channel 3-10 is DESTROYED! Someone butchered this tuner. UGH! When I got the turret out, it sounded like shaking a jar full of pennies. Pieces everywhere. All the tuning screws were driven in too far, destroying the tuning abilities for all these channels.

So on the hunt for a late 40's/early 50's Admiral turret tuner.

Over all, a decent first power up all by myself. Lots of bugs to work out, but there is life and nothing blew up. I did not really mess with the phono at all. When I switched the radio to phono mode the turntable did start turning with a little kick start from me. So it had power too.
