Re: Two Rock Power Supply Question
Hi,the "D" on the picture is a different rectifier from the PT for the reverb..In the custom reverb it is b+>choke>screengrids > PI > OD > IN with a 10K from PI for the reverb driver..In the classic reverb i think the MiX tube replace the OD and the "D" rectifier is for the "Send/Return tube..

Re: Need Help. John Mayer sig. Amp.
HI,first the power supply :there is two rectifier ,i tihnk one is 420 b+ (like classic reverb)and the other is a lower voltage (from pt) that goes to a 47uf cap only for the reverb V2(to enhance 3d effect and prevent loadind) ..the rest is like the dumble power supply 2k2/22k/2k2 but there is a 10k ...
