Recently was gifted this Amp. Cleaned her up and she works well save for the power telltail lamp.
Bought proper 14w 50ma grain of wheat.
Looks to be glued in? Any pitfalls you guys know of? Total rookie here.
Thanks!
Doug

Nice amp :)

I'm not going to commit as to whether your bulb will be OK because it depends totally on how it is configured electrically.

Some of these tiny bulbs have very limited life, something that can increased dramatically by adding a small resistor to drop the voltage a little.

For example a bulb with 100 hours life at 14 volts may well last 500 hours at 12 volts and perhaps 3000 hours at 10 volts. Its not linear.

You might also use an LED successfully (with resistor of course).
