Jet engine Igniter box repair

[Ted]

I need to fix an igniter box, I suspect it might be the high voltage
rectifier, what modern equivelent could I use for the rectifier diodes?
The box is a rotax type NB 25/3, 24 volts in, 2kv out, 12 joules.
It's a simple circuit comprising of a trembler mechanism, induction coil,
rectifier, choke, reservoir cap, discharge gap.
When I apply 24v, the trembler buzzes as normal but no high voltage. Any
ideas?

Try a rectifier out of a microwave oven....
