Just restored this oldskool Audiobahn bandpass box wasn't working paid 30 dollars.
All wiring and terminals were corroded and neon light didn't work. Spent $20 on new terminals, rewired the wiring and bought an led neon for $11 wired it in and mounted it in a different spot. Re-sealed the perspex cover and new screws.
All in perfect working condition now.
