- After more than three years of faithful, dependable service, the 9425 power supply gave up. T-shhoting revealed that R2 on the 81212 Rectifier had opened (big crater). According to the manual schemat

- sounds like the R2 failure was a current limiting resistor, to not apply a big surge to the associated rectifier. Stuart Rohre K5KVH _______________________________________________ TenTec mailing lis

- Yeah. The relay and cap on the load side of R2 test good, and other circuitry on the source side is healthy. The failed R2 still has piecemarking legible: HE19316, RT-25, 20 ohms. Don't recognize the
