  • S80 M80 neon tester substitute

    What the heck is a S80 or M80 tester (required to test amplifier on 71 Johnson V4100hp) and is there a substitute I can use to test amp?

    a decent subsitute is the stevens CD-77 peak reading multimeter. you can measure primary coil voltage and look for intermittent voltages. however the CD-77 wont place the load on the amp that the neon tester will.
    no tech questions by PM, they wont get answered.
    you have to be trusted by the people that you lie to .
