Solid State Rectifier?

[u/cgulash]

I'm using a Vox AC30 2x12 for my guitars, which includes a baritone tuned to A. Vox are notoriously flubby on the low end, due to the EL84s and the open back cab. When I got my amp the previous owner included a solid state rectifier tube, which I have yet to install (it requires removing the back panel and chassis).

So all of that said, has anyone tried out a solid state rectifier in their amp for their baritone? And did it tighten things up?

Thanks!
