Help sourcing two resistors

hotrodjohn71 · Jun 28, 2024

Hi group.
Can you help me source 2 resistors I need for my 57 Ford truck radio?
Ive searched for about a half hour but am coming up short.

One is a 680k 20% 1/2 watt
And one is 15M 20% 1/2 watt

Thank you

somethings missing as I must be blind as I can't find A5, A6, A7, A8, tuning inductors.

In what looks to be a variable inductance tuner unit? The big section above the wax capacitor in your first photos?

Here are some photos of the tuner unit when I removed it to change the wax/foil capacitors underneath it

I take alot of photos when I work on things.
.
It has 3 'tanks' that have shafts that simultaneously go in and out driven by a worm drive gear from the tuning shaft.

Its hard to see all tanks from any single photo.

the big top tank has a green and white wire which is supposed to be 13 ohms.

otherwise, there are a group of about 5 or 6 tabs that govern the other tanks which solder into the main board.

It was said in the video I referenced earlier that they were factory tuned.
