Question for all you clever tech-heads;
Amp Model; Gibson GA 5T 1960 model; tube line up;
1x 12AX7, 1x 6BM, 1x 5Y3.
In "Inside Tube Amps" by D. Torres, he states one can change a 5Y3 for a GZ34, rectifier tube.
Is this so?
The reason I'm asking is this; The amp sounds a lot better with the following filter caps; 40uf/500v; 20uf/500v, 10uf/500v.
As opposed to the 20uf/500v, 10uf/500v, 10uf/500v, that are specified on the schematic.
In the above book, it is stated that 5Y3's cannot have more than a 20uf/500v filter cap in the first filter posistion.
So, to sumarise; do I need to change the rectifier tube to a GZ34 if I wish to use the larger caps?
