I tested mine (mid-'90s, Chinese made) and it has a low trigger voltage of under 10V. I have been using it with my R-D1 and LC1 and there has been no problem. I agree early 283s ('70s, Japanese made) had very high trigger voltage, in excess of 200V if I recall correctly. Joseph on 30/1/05 12:46 pm, Stan Yoder at vze2myh5@verizon.net wrote: > Be careful.
