Fender Prosonic can switch to SS rectifier, will this bypass a bad rectifier tube?

My Fender Prosonic is experiencing whisper low output. I've checked all the tubes except the rectifier because I don't have a GZ34/5AR4.

It still doesn't work in SS rectifier mode, doesn't this save me the step of testing for rectifier tube failure? I assume a healthy amp would work fine without a rectifier tube if in SS mode.
