IN-14 Nixie newbie

[phillip virgo]

Hi guys, im phill, ive just built an IN-14 nixie clock, have tested throughout, 4.7V on low output, 174V on high output, 12V input, everything went well, tested tubes, all fine, now to main power up and nothing, only 12V input is reading, there are 3 main diodes, 1 of wich appears to be shorted, so replaced, new one immediately shorted, all solder work appears fine, i cant see any bridges, sould it be possible i have a crack in the board, or just faulty diodes? Also have checked all resistors are reading correctly, i got the kit from pvelectronics who are very good from what ive read, thanks.

Hi phill,

Have you tried asking Pete Virica (PV electronics guy)?

He's probably most familiar with the intricacies of his design.
