Load Resistor on Reverb Driver: opinions?

[dcoyle]

Most Fender circuits use a transformer hanging off the B+ to drive the reverb tray. I recently worked on a Rivera era Super Champ that used a load resistor in between the B+ and the S.E. transformer, 39K for the SC, and Rivera's Deluxe Reverb II uses a 10K. This slight increase in fidelity seems attractive to me as a concept, but I have no way to A/B it right now, and am curious if others have explored this and formed an opinion?.

Increased fidelity? In a reverb?

The Super Champ is a model that has the option to use the reverb drive circuit as a boost. So they added that resistor in the plate lead to act as a load under those circumstances. I see no benefit adding such a resistor to existing plain reverb designs. It would only tend to dilute the drive in my view.

You've got it , that's why the resistor is there. Thanks, Enzo.
