Title: Sarah’s 12AU7 voltage Post by Rhtubes on 07/04/24 at 00:45:46 The standard 12AU7 can operate on both 6.3 and 12V. Brimar’s 13D5 only uses 6.3V. Does anybody know how Sarah’s input tube is wired?

Title: Re: Sarah’s 12AU7 voltage Post by CAJames on 07/04/24 at 02:23:55 I think 6V, because I (vaguely) remember the Decware transformers having a 6V but no 12V winding. But obviously emailing Steve would get you the right answer.
