Re: Tek 2230 psu story (work in progress)

Update, the new t948 has arrived but not before i managed to burst another componet, a zener diode this time (1N475A) 6.2 voltage reference in the inverter section seems to be the only fault this time but since im at it ill replace all the electrolitic caps with some new good low esr ones. BTW the fail (open not shorted) of the said diode seems to result in a similar cycle of the one induced by the crowbar circuit (witch it was removed on my scope) but with the neon spark-gaps that do not operate.
