    Btw, I have a tweed hot rod deluxe extension cab I never use (I don't have the HRDLX amp anymore) that I'm pondering turning into a combo cab for the 5e3. I'd have to build a 2 piece back panel to replace the closed back one and cut out for the chassis. It's a 1x12 but it's big enough to recut the baffle to a 1x15 or build a new baffle as a 2x10. It's unfinished tweed so I just wonder how hard it would be to pull back the tweed, cut the chassis cutout, reglue it then shellac/laquer the cab. Has anyone here tried lifting then reglueing tweed onto a cab? That's my only concern is getting it up enough to cut out for the chassis without tearing the tweed.

    I know you didn't ask, but personally I'd consider a matching head to go with that cab.

    I've actually been thinking about building a head cab and covering it in matching tweed. I will shellac/laquer them both if I do. I also thought if I did I might cut about 1/3 of the back off and make a removable section to make it open/closed back convertible. It always seemed like tweed type amps sound better with a open back cab.

    Ampeg makes a flip-top bass cab. You can attach one of several amp heads to the cabinet and you flip it out to play or flip it in to transport/store.

    Never seen a guitar amp like that but it would be cool.

    A flip-top guitar amp would be cool. I've seen the Ampeg bass amps and it is a good idea, it makes a more compact amp to carry without losing cab volume. The size of the standard 5e3 cab is really on the small side, I know they were never intended to be run at the volume people run them at now though. They were designed back when overdrive was still considered "unwanted distortion".

    I sit down and drew a layout for my build with the minor mods drawn in. I'm not planning to do a lot of mods, it's easy to get where I'm spending more time playing with switches than playing. Once I find the sound I'm wanting from the amp there's no reason to have a hundred other options anyway. I do like a grid stop resistor on the phase inverter and a NFB loop option to add a little headroom, and maybe add a little more filtering, those are the biggest mods. I wouldn't mind adding a mid-cut but I don't want to delete the tone to do it so I'd have to make a place for it.

    I checked my voltages again today and the B+ voltages have increased by 10-15 volts since the last time I checked. I haven’t made any changes. Is it normal for voltages to change?

    I'm interested in what everyone thinks about that too, I haven't had a lot of experience with cathode biased amps so anything I can learn helps, especially since my kit is supposed to be here Thursday :)
    I do know that tubes themselves will fluctuate a little after 24 hours or so of use. From what I've seen modern electrolytic caps and film resistors don't change much at all with "burn-in". Those big paper red Atom caps from the 60's look cool but I really like the way the modern ones perform, I've heard they're supposed to last 30+ years before you need a filter cap job.

    What is the wall voltage at your house?
