Hi all
I am working on a pioneer a9 amplifier and am trying to figure out what wattage this Zener diode D5 on the regulator board is rated at I think its 14V but can't find any info on wattage rating for a replacement
the part number is KZL-140 and I think its 500mw but had to ask
thank you for any help!
Terry

I was not sure if 1/2w or 1w, there is no listing as far as replacements to match this number, I was kinda wondering if it was some sort of special custom production for pioneer but I also see the same zener is used in other areas of this amp, I can't find 1W versions and I don't know how well paralleling 2 of 1/2W versions would work in this circuit
