Default Re: Pye B18T found, how did I do?

Jake are you saying the SU61 has no heater continuity?
If so an EY51 is fine as a replacement. It doesn't matter what way the pair of lead out wires are connected.
Before you do this you need to establish if you are you getting any line drive or EHT? do you have any line whistle? The SU61 heater will not light unless there is EHT present. Check also the heater winding for continuity.
