UM35 Umbau

Das Leuchtbild der UM35 und der Durchmesser stimmt mit dem der EM35 Überein. Jedoch ist die Heizspannung höher (12,6 V) und die Sockelbelegung anders. Mit der Delonschaltung (2 Dioden zb.1N4007 und 2 Kondensatoren 35V 470myFarad) kommt man schon auf die Heizspannung. Für die Sockelbelegung beide Schaltbilder ubereinanderlegen vergleichen, umlöten fertig. Es müssen keine weiteren Änderungen vorgenommen werden.
