Here's a link to a video clip of what is happening when I turn the reverb up on my Fender Custom Vibrolux:
https://db.tt/UmDKMz1EIt's been like this for a while. This morning it was fine, but after playing for 20 minutes or so, the noise crept in. The reverb is still working underneath it. It has also presented itself as sounding like gusty hurricane as opposed to more constant white noise.
The reverb valve has been replaced, but what's weird is when I removed it earlier and adjusted the reverb, I was still getting the noise coming through the speaker.
I did some of the Mark Moyer mods to this amp to reduce the hissing when I first got the amp, and it was fine for ages. Maybe something it what I did finally affected it?
If anyone has any suggestions as to what I could do to try and diagnose this I'd be mightily grateful. I appreciate it might not be possible to tell what's wrong just be listening, but any pointers before I bite the bullet and pay someone to look at it...
Thanks.

Here is a link to the mods:

Note that I didn't install a bias pot or remove the surge protection diodes.
This link I used at the time too as it has some pics and tracks progress of someone else doing the mod:

Do you have a spare RCA lead to try?

chaps I think you might've solved it - took the reverb tank out, evacuated the resident spiders, swapped the RCA cable and...silence! (Well pretty much, there was always a bit of residual hiss)
I am cautiously optimistic and assuming it remains that way after further testing, massively grateful!
