Vox AC15 FX LOOP

[rczcustom]

Hi!

I want to install this https://www.tube-town.net/ttstore/kit-serieller-fx-loop-lnd150.html or this one https://store.metropoulos.net/products/zero-loss-fx-loop-kit


I understand all the schematic but I don´t know where is the B+ in the AC15 C1.

Some help pls?

This is NOT your exact schematic but simply an example to illustrate the "B+ rail". 

The "B+ rail" is what is coming from the rectifier (tube or solid state) and goes to electrolytic filter caps with dropping resistors between them which help lower the voltage.  Sometimes there is a "choke" between the 1st and 2nd filter cap.

That's simply a starting place to think about this.  B+ is the voltage that has been rectified that powers the tubes.

With respect, Tubenit
