Add LEDs to Vintage Radio?

[w0z]

Someone said in an earlier post that I had to run in parallel rather than in series because the PS was constant voltage instead of constant

Parwallel is fine, originally i thought you said 9V which is why I suggested series as up to 4 or 5 in series at 9v with a series resistor would have worked with LEDs which had no series resistor integral with the led, but now I see the supply is 5V and the LEDs have series resistors already so run the LEDs in parallel.
That has nothing to do with my comment about the potentiometers, So parallel the lamps and put them in series with 2 of the potentiometers terminals, then when you’ve set the pot. To the satisfied brightness, disconnect the LEDs and measure the resistance across the 2 terminals of the potentiometer, and replace pot. With a fixed resistor of the nearest preferred value. Is that any clearer?

Gotcha. Yes. Thanks!

Hi all. I am trying to figure out how to add a few amber color LEDs to a 1953 Zenith K622 radio. One to light the tuner, one for the clock and one behind the center grill. I've gone down some rabbit holes. At this point, I would tap the original 110vpower and connect an 110v AC to 9v DC step down power converter then, from that, parallel wire three LEDs after three resistors. Does this sound right???

Welp, after much learning....this is how it ended up looking. Thanks for all the help fellas.
