to light up the display. You need to find out the lamp voltage and the current you want for the white LEDs. You need to use a soldering iron. A display lamp dimming after warm up seems like a bad connection or resistor somewhere. You will need a volt meter to probe.
Wow, a Mac 1500 is Old!
Solid State preamp, Vacuum Tube power amp.
Watch out for those high voltages. Get an amplifier Tech to look at it or wire your own USB/LED lighting system if that is the only thing bothering you. You could use a wall wart and just power a pair of LED with a pair of wires.

It sounds normal to me if you are NOT using the FM section. See what happens if you use FM. )MT( - J. S. Bach 15:17:06 10/26/24 (1)
