Marantz Model 19 Power Supply

[sherryryra]

Hi, I am rebuilding the power supply on a Marantz model 19, I am looking for a replacement for the CR111 and CR112 which are zener rectifier 36v 1% 5 Watts and a silicon rectifier cr101 1500 piv. Any help would be greatly appreciated. Thank you

I don't think you're going to find 1% in 5 Watt dissipation. 5% is good enough.

For the rectifier, I don't know the current rating on the original so I'd go with this one:

I have used those exact diodes in 2 of my Marantz model 19's and they work just fine.
