2019年2月13日 · As part of my repair I decided to test the STV-3 diodes on both boards. The expected voltage drop on my test rig was 1.5 ~ 1.8 vdc. The voltage drop I measured was 2.2 vdc. I got this on all four of the diodes off of the two boards. To verify my test rig I tested a diode from the supplier in Germany who is selling on eBay.

2020年6月14日 · Has anyone found a good solution/replacement for replacing Sanyo STV-3H Varistors? I repair old stereo equipment from the 70's and this was a common part in many amplifier designs from several popular manufactures. Sanyo stopped manufacturing them years ago and has no cross reference to a replacement. Thank you.
