  • B&H 535 Projector Tube Amplifier

    This is my first post. Does the switch panel indicator lamp need to be in place before energizing the amplifier. Looks as though filaments are in series with the lamp. The one that came with the projector was burnt out. Filaments won’t light. I changed out the electrolytics and tested all components. Electrolytics were bad, one was leaking physically. Everything else tested good. What is my problem? RDub…

    I figured it out. S1 is not conducting to the amplifier. Tubes are in series. Indicator lamp has its own circuit. Now to find a donor circuit board. 🤨
