The reverb on my Fender Blues Jr stopped working. I have 0 experience working on amps and am hoping that just swapping out a tube will fix it. (I know the specific reverb tube in my MesaBoogie, for example)

I Google'ed the Blues Jr's tube layout and just find a barrage of schematics info, making me think this amp doesn't have a tube dedicated to just the reverb.

With three 12AX7s and two EL34s....does anyone have any insight on a which tube might be tied to the reverb?

Thanks!

There is no reverb tube, as it is a solid state driven reverb. Did you try to plug and unplug the cables to the reverb tank at both ends of it? Did you recently drop the amp at all? The springs in the reverb could have came unmounted. If all else fails you could always order a new reverb tank for cheap.

Thanks! That explains why my searches usually including "reverb tube" were sending me astray. No drops with it...so I'm going to poke around what you mention. (it sounds pretty simple)
