I've been having some problems with my z-28 recently since a fuse blew (venue voltage problem). First I needed to change the speaker since it sounded as if the speaker was exploded; excess unwanted vibration etc. I bought a warehouse speakers g10c/s it is supposed to sound beefier. Yet in my opinion it sounds thin. I have no clue if this might be that the speaker is not broken in yet or if its a tube thing. Ide appreciate your help.
*Hey guys, following up on the Z-28. It was not a tube nor amp problem. It was the new speaker. The WGS G10C/S took a bit to relaxe and still needs some more power stretching in my opinion. But the amp is definitely blooming. New speakers suck without a doubt until they settle in. I was preoccupied because in my experience the speakers I have bought before didn’t need too much stretching to sound good but this was a great example of the importance to wait for the speaker to break in. Sounds great. I’ll post a vid in the future. Thanks!

Thinness makes me think tubes..power tubes, since you already did the Rectifier. But the speaker blowing doesn’t seem consistent with a fuse blowing. Maybe you need the original speaker to die if it’s the speaker change or the tubes.

I'd recommend a full tube checkup. Get your tech to check the bias for your power tubes (6V6s @28ma). If you don't have a tech you can swap the V1 (EF86) and V2 (PI tube 12AX7) with different identical tubes and see if the tone changes. That means use another EF86 for V1 and 12AX7 for V2. Preamp tubes don't go bad frequently but a quick swap can rule them out. I recommend doing one at a time to see if anything changes. The WGS C/S is a thick speaker IMO. I have one I've used in my Z-28 and it has a bright but smooth top end that will open as you use the speaker. The low end is great and it makes the '28 sound more Brownface than a Celestion.
Did you figure out what was up with your '28? Curious....

GuitarZ: They say you should be on the same page about kids before you get married. I really think you ought to talk about expectations on outdoor Christmas/Holiday lights. That could have been a game changer.

GuitarZ: Arggh! We had it on the calendar to stop out and see you but got caught up with holiday stuff. I could have met you & Frank & my wife could have connected with her friend from back in grade school. You snooze you lose. The FB videos sound great!

GuitarZ: Why is it once you finally clean the junk off your work bench, within 5 minutes, you find yourself ready to deposit some other junk right back on to that now clean space?

rossco: the variable e.q bypass is great because while bypassed it you get the raw sound of the amp without the e.q and everything else attenuating the signal which sounds great and a because its variable on the foot switch you can dial in to taste, 1/2 way I like

rossco: you don't have to fully bypass the tone stack which is great because gives you room to dial in your sound, it certainly thickens up the sound and adds nice growl/midrange growl. I don't like pedals so this replaces everything for me

easyed: It seems that the only time I clean off my workbench is when I need the space for something else. If I don't take a break, it's less than 5 minutes before that space is full again.
