Dynaco 120 diode replacement

[tsd71]

Hi I'm working on the dynaco st 120 and I have found a bad Zener diode. It is D1 on one of the amp boards, it is described in the manual as a Zener diode, 5.1 volt, 5%, 400 mw. Can anyone recommend a replacement, I'm not very good at matching diodes. Any help is greatly appreciated. I have some 6.2 volt 0.5 watt Zeners, would this be ok to use? The part number is 1N5234b.

Thanks

No, you need the correct voltage. Use a 5.1 volt zener.

Should be ok.
Just make sure you've confirmed there is nothing else that has failed along with it.

Thanks Glen, got a couple of bad transistors too. I have replacements for those.
