Re: 2215A LVPS repair


 

Hi all,

Quick check of the FET's learned this:

the recommended IRF730 has a input capacity of 620pF
The ordered replacement IPA60R280E6 has a typical input capacity of 950pF.

Time will tell if the transistor driving the FET is able to drive this larger capacity.

For what it's worth: the broken FET I found in my scope when I got is was a IRF710 (400V 200pF...)

To be continued,

Un saludo,

Leo
