Learn to Troubleshoot Tube Radios - Step by Step 

A great primer indeed. Thank so much for sharing your time tested knowledge. Much appreciated.

Thank you. Great video.

Excellent video. Thank you for sharing your knowledge with us. I have booked my front row seats.

Great video. Great demonstration both theory and practice.

Very good video. Nice set of steps and tests. I'll be using this process and procedure in my restorations. Thanks.

Thank you, great job !

We’ll done

It may help some to show where you inject the 455Hz.

Thanks for great video. On that B+ thing, in other countries like Europe is named as Constant Corrent, few countries call it Direct correct. My Daughter is a electrical engineer and she asked me the other day. What the heck is B+. I said it came from Batteries. I rather say positive +DC or Negative -DC to avoid confusion. It's just my preference.

What is the model number of the function generator. Great video very interesting.

my FM is not working, it was for a few minutes then it die on me, my radio is a loewe opta telefunken. what could be? the ECC85 is good for FM

i have what appears to be a bad solder connection except i sucked off and reheated every single solder connection in the radio. I also cleaned all tube pins and sockets. Replaced all resistors and caps. yet i have an intermittent crackling and sensativity issue. The sensativity comes and goes. poking in the radio and wiggling does nothing. Moving tubes does nothing. But if i stand in the center of the room and lightly tap my foot it will crackle and reception will get better or worse. just like a bad solder joint. hitting chassis or tubes does nothing. only standing in room and hitting my foot on the floor or rolling my desk chair across the floor will cause the reception (connection issue) to either improve or get worse with a slight crackling. im at a loss what to do

Is the radio powered on when using the signal tracer?

I have had a couple of beginners ask me what to use for tracing if they have no equip,emt yet. They also don't hve the RF/AF switvhable probe. Any tips?
