EUGINE! I think the primary on that unit is center tapped. Maybe they (CIRKITS) substituted the 87bx135 with with it?
That means the second half of the Primary coil is being shorted out by the circuit board and it still works.
As per the schematic, the coil is not center tapped. This is a most uncrittical circuit.
It's just a voltage pump.
I really think any of the YOKO yellow IF coils would do the job as long a you keep the Driver Transistor within it's Ic limits.
100ma!
No Big Deal.
ToKo must be owned by the NSA, CIA or some Cartel.
There is like (0) information on this coil.
I would just wind my own on a old TOKO form.
Worst thing your going to do is toast the driver transistor.
Some one should spit this thread off. I feel like a thread Robber!
