im repairing a Luxman L-210 that i picked up at a garage sale. turns out that one of the resistors and zener diodes shorted but when i looked up the parts list in the service manual it says "HZ22-2L Zener" for diode D-112 (number on the amp board). I've tried searching up the description and the stock number itself but couldn't find any actual values for the diode, so im having trouble finding a replacement. If any of you have worked on luxman amps or know how to find a replacement any help would be appreciated.
