Title: About Rectifiers - Can 5R4G replace 5U4G? Post by bmoze on 02/08/23 at 20:12:24 I’d like to verify that a 5R4G Rectifiier can replace a 5U4G. This is for a Torii Mk4. I thought I had seen in a post here that it could, but couldn’t find it again. Thanks. |

Title: Re: About Rectifiers - Can 5R4G replace 5U4G? Post by CAJames on 02/08/23 at 20:52:46 It will probably work fine, IMO. The 5R4 is in between the 5U4 and 5Y3 (or type 80) in the rectifier hierarchy, so if you'd use a 5Y3 in your amp then a 5R4 will be fine. The concern is that is it only rated for a 4 uF power supply capacitor. But I've used them in in my UFOs with no problem and I fell like the maximum current rating is very high and in general old stock rectifiers are really robust so I wouldn't hesitate. But the JMO/FWIW/YMMV. |
