Thanks again. I won't forget shunt (and series) resistors for the dial pointer LEDs.
I did remove the 100 ohm 5W resistor, yes. I forgot to mention that in post #23.
As far as I can tell, Auto Magic is a fancy name for AFC. The meter does not change color from green to white when I touch the tuning control, but the receiver stays in tune over a large range if you turn the tuning knob to the left or right somewhat with Auto Magic turned on. Sort of like a properly restored 1937-38 Philco with Automatic Tuning does when the Automatic Tuning control is turned on - it keeps the receiver tuned to the correct frequency.
I've been buying my LED fuse lamps from eBay seller projectblk86, also known as Joe's Quality Wholesale. He has fuse lamps in warm white, blue and green.

I see he is now selling bi-pin lamps in LED and incandescent form for Marantz receivers as well as dial pointer lamps. Didn't know he had these - I just bought a kit of bi-pin LEDs and a dial pointer lamp for my Marantz 4230 from someone else.
Yes, I think LEDs look much, much better than incandescents. Especially in this Realistic - the original incandescent bulbs were very dull and lifeless. The LEDs make the STA-225's dial look in a way that Radio Shack could have only wished they could have looked in 1975-76.
