Hi insanity, Thank you for your help!

Just finish my PSU, everything working fine but I've questions about measuring Bias voltage. There is measured 576V@Bias TP(570V before 4.7M resistor), but 380V@Bias out. (I use Mini PSU board) Is that working correctly? Thanks! Pal

I've done BOM for KGST, may please double check. Thanks! https://docs.google.com/spreadsheet/ccc?key=0Ah_gUy3jQOfTdEtNLURhTEtEQnJxNDVydjgxaU95SVE&usp=sharing PS:The LED P/N is 1.7V that I copy from Tran's BOM. But Original KGSSHV's P/N is 2.1V. Need confim for this.

Got some 2SC3675 5B2 and 4C1 looks good, but not sure 7D2. All test good above 1000V+. May help to inspect these? Thanks!

Justin, thanks for your pics. I'm thinking another source for 2SC3675.

Received some 2SC3675 but they looks not like normal. I can't make sure it's real or fake. I've test voltage breakdown, all 1050V+. And hFE is 35+ Should I find another source? Thanks! Pal
