Explanation of the Terms
TR = Time taken for current to rise from 10% to 90% of its peak value
This factor and the rate of current rise (slew rate) * determine the amount of noise reduction in the lamp.
Vd = Voltage drop due to choke. (See circuits 1 and 2)
Tr = Approximate temperature rise. (Convection cooled)
+15
L = Low level inductance
-7.5%

Terminology
Vp = Primary side of transformer T-1
Vs = Secondary (Low voltage side) of transformer T-1
VL = Voltage seem at the load (Lamps)
Vd = Voltage drop due to choke (Vd = Vs – VL)
L1.L2.L3.L4, etc. + Debuzzing chokes. May or may not be the same type. **
*Foot mounting may be cut off at factory or in the field and the center mounting hole be used only.
