identifying zener diodes in schematic ?

[maxs]

im having trouble identifying 2 diodes in the schematic below ive built the entire project but ZD1 (152) and ZD2(302) i cant seem to find out the values although ZD1 is a 12v zener of some sort and ZD2 is i think a 40 + v zener but not sure ....

oh and R49 is also not labled in the schematic i used a 15k but its probably not correct

any help would be great thank you...

Just wild guesses here but I would have thought 15 volt for the 152 and 30 volt for the 302 (probably to cutoff anything for 12 v and 24 v that is over 25% ) and an even wilder guess for R49 would be 47k. There are some others around here that can probably give you more help.

yeah i was going with 47k on the resistor but desided to test the 15k and was going to test 12,15v zener on zd1 and test 30,33,and 40 and above for the zd2

thanks for the quick reply
