- Notes
-
On models manufactured after the 11 May, 1936 the automatic bias on the 75 valve was replaced with fixed bias. The bias was obtained from a 30Ω tap on R14. This necessitated the addition of a de-coupling resistor of 500kΩ (connected between the lower end of R8 and the 30Ω tap), with its associated de-coupling capacitor of 0.1uF connected from the junction of 0.1uF connected from the junction of R8 and the same de-coupling resistor to earth. Also C22 (0.006uF) was increased to 0.1uF.
