National HRO Receiver Serial 124B Video #2 - Power Up Test

I cautiously begin applying power to the receiver. Will it work?

Pull and test tubes, I always test tubes before power up. Put a signal into radio and test each tube in order for signal and strength.

What's the goal here? to test if it works, or to restore the unit? I guarantee it will work, there is not much to that receiver, its simple. Your best bet would be to completely restore it. New resistors and caps where needed. Do an alignment including the coils. Oh and the knob, don't force it, remove the top plate then pull out the front gear and re-lube (grease) the top gears and put them back together. Those receivers are bult like tanks they work they just need some TLC and allot of elbow grease!

You forget to switch off the crystal filter until Your noise test.
