Ron's RCA T7-5 Electronic Rescue
#50

Okay!

Tonight, I finished up the third electrolytic can and installed it.

I also finished connecting the speaker wires, the B- leads, and the 6K7 RF tube grid cap lead.

In addition, I went ahead and installed the 15K resistor in place of the original 13K (R20).

And, of course, a new AC cord and a 1930s AC plug were installed.

I tested all seven tubes. Of the seven, four required replacement. It had a 6V6GT in the audio output socket and it failed its test anyhow; it was replaced by a metal 6F6. The 6K7GT IF tube was weak as was the 6F5; the 6H6 had one dead section. All were replaced with metal save for the 6H6 which was replaced by a 6H6GT as I did not have a metal 6H6 in stock. But that's okay...I intend to open up that little top hat 6H6, gut it, and install two 1N34A diodes inside. I will then put it back into the radio.

Two of its original Cunningham-Radiotron metal tubes tested good and remain in the set: the 6K7 RF amp and the 6A8 mixer-oscillator.

Here's how things looked by the time I had installed everything:
