Hi Pete,
I've recaped 2 of the model 20s. The large filter can is not too bad to add in the new caps, right in the bottom cover. Snipping the wires back you should have enough room.
That would be the first step, and you just might receive stations after that step. Then, on to the other cap and out of spec resistors.
A fuse would be fine, in case something this side of the primary shorts out. But if something in the secondary like the filters shorts out, the fuse might not 'see' the current draw of the secondary, and continue to self destruct.
I have a couple of photos of how I installed the new caps, I just have to find the image in one of the older posts. You don't have to use electrolytics like I did, you can use film caps (non polarized) ad they will work fine. I used them on the second 20 I recapped.
So, you heard no hum but it had audio? Just white noise, or?
I'll check back.
Gary.
