Hello. I have a Tenma 72-320 scope I bought with no trace, got a trace back but the trace is spotty. One of the "Y16GA" diodes is cracked. I contacted Hitachi and they said there was a Y10GA but not a Y16GA. The datasheets they sent indicate that Y10GA is 6 KV, and Y16LA is 10 KV. Forward voltage of 22 volts Io 5 ma and 35 volts Io 3 ma respectively. I've sourced some diodes with higher forward current and reverse voltage ratings, but the forward voltage is lower like in the 9 to 14 volt range. Will that cause an issue or do I need to try and find an exact match even on forward voltage? I intended to put the 12 KV diodes I found in because the parts list and Hitachi revelation, along with the fact that the diode on the board has a yellow band, which isn't shown in any of the Hitachi datasheets leaves me questioning what I'm actually looking at, so I wanted to err in the higher voltage and current direction to hopefully save my butt. By the way, does anyone have anything that shows that there IS a Y16GA?
