National PE-387S Flash Gun

[tenala]

can anyone advise where i can get a circuit diagram for this unit or
alternatively explain why gives a constant low output choose what ever
settings its on i.e. max or min gives the exact same output. changing the
main charging capacitor has made no difference.

regards
gerald
