Hello, all... Thrilled to be here...Recently picked up a used Z-28 head and matching cabinet. Simply Incredible is all I got!!! I was looking for, and found incredibly full and rounded clean tones, which was my goal. (I used pedals to add flavor). A few weeks after purchase, I blew the fuse and 5AR4 simultaneously. (...while playing, not while powering up, if this makes a difference). I replaced with proper fuse and 5AR4 with another new JJ. It now powers up and sounds fine, but has possibly lost a little volume, and definitely breaks up before it did before.
When first purchased, I ran all 3 knobs straight up noon, and was in clean tone nirvana. Now, when all knobs at noon, it has more crunch than before. Still sounds great, just more dirt. FYI...My 6V6's each has a "6" on it...Some of this tube stuff is new to me...any recommendations to get back to the fully clean tone???
Did you replace the power tubes at the same time? The power tubes may have caused the rectifier problem but the power tubes wearing out would explain your loss of headroom.
Remember, when you replace power tubes on the Z28 you will need to re bias the amp or have it done by a tech.
hope this helps, Todd
by the way, big fan of the Z28! Great great great amp!!

I always buy matched quads and have it biased. That way when the tubes get spent, I can pop the other 2 in and be good for that much longer. Cuts down on tech time and money if you dont do biasing yourself.
I always replace power tubes in pairs. If one fails, it gets 2 new ones. I dont always replace the 5AR4 with tube changes, but if I'm GOING to, do that at the same time as biasing. FWIW, I had a Shuguang 5AR4 in my that started rattling, and I just pulled and replaced it with no issues. Recto tubes either work or they dont, but they do go bad, so unless you got a NOS Mullard, etc, it's not a bad idea to replace them occasionally. They're under $20.
Changing The EF86 and 12AX7 probably wont do much in your situation.

GuitarZ: So, I cranked up the privacy protection on my browsers, facebook, etc. I have to say I miss the music ads and such. I really don't need ads for watches and other random stuff. Maybe the internet knowing me isn't such a bad thing.

GuitarZ: Reminds me of buying my Honda. When they tried to sell me the maintenance package, I said "Is your car not reliable?" Long story short my wife teamed up with the sales lady to buy the maint package. Never again!
