Now you need to start checking voltages on your tubes according to the diagram in Fig. 1 of the service bulletin. Note that these voltages are taken with an older 1000 ohms-per-volt VOM at 115 volts AC mains. With a newer VOM or a DVM (and also higher mains voltage) they will be appreciably higher.

That's why I have 1000 ohms-per-volt VOMs on my bench to make sure I match the original mfrs specs with sets that specify how the voltage readings were taken at the factory. Icon_smile
