Thanks Duncan !! A bit hard to to read but a good start ! I had found that other post already - his heater wiring looks a little skimpy to me ?

Your right at 6.3 volts thin heater wiring can heat up due to higher resistance ,I always used thick wire .


I can increase the magnification on my PDF app in my LInux distro but your right a bit indistinct you will be lucky to find another one online , it took me 15 minutes and a special search engine to find it.
