Powered PA mixers are flipp'n great for Synth amps.

I use a Yamaha EM 200 Powered mixer form the early 80s and 2 of those Rat Hair Yamaha stage monitors. I got the mixer for, I think $45 and it is great at being an 8CH synth amp. It's Stereo. It has Spring Reverb! I also use a little 10" JBL home Theater Sub with it. It has been plenty for practice room play. I'd get a bigger sub if I was playing out. The Mixer is fucking really loud. It als give you the ability to add more powered speakers through the aux or group faders, and plug in a mic if you want to yuarlp into a delay pedal or something.

I think a Powerd PA cab and Sub is the best Synth by any measure. You kinda want a full range, minimally filtered set up for synths usually and guitar and Bass amps dont really do it anywhere as well as a Little PA set up. A QSC K10 (or anything like it) sitting on top of little powered sub would work great. You can add a second for stereo if you are into that sort of thing. Powered mixers are my pick though.

Loose tube socket. I even had it replaced but the tube (replaced as well) still wiggles itself out on the reg. It’s a quick fix at home but it would be annoying AF for it to happen on stage.
They should have a V shaped bracket on the tube socket that have teeth to grab onto the tube base. If so, you might just need to pinch those together more (with the tube out) to have more contact with the base. If that doesn’t instill enough confidence one can add the spring tube retainers instead. These are super cheap parts.

If they’re falling out like that your sockets also could use a retention, I do this with a tiny screwdriver / if you have a multimeter check to make sure they aren’t getting DC voltage on them first! (Which can happen if you ran it without tube connection). If there’s enough DC you can arcweld your screwdriver to the socket receptacle.

This is a great idea and they can be gotten for cheap-as-chips. The Yamahas are good and the old Mackie 808 was a good'n too.

The only drawback w/ going the powered mixer is expansion. You're pretty much locked into the box. If you wanted to add a sub down the road, it might not sound super great because you'd be sending full-range to the tops and also lows on the bottom. Could end up with all types of weird sound/phase stuff happening as a result. IDK, I might be overthinking it.

Many powered mixers such as the Mackies have a secondary or assignable graphic EQ that can be used as a low pass filter. I have used a cheap Kustom 4-channel mixer with very rudimentary controls as the power amp for my practice space subwoofer, and all I did is turn down the treble and mid on the 3-band EQ and it sounded just fine.

It really depends as features, especially routing & outputs vary wildly from model-to-model. Almost all the powered mixers have some additional expansion/aux send options and eq, but to be clear using an EQ is not the same as a crossover as it doesn't completely cut, just reduces...which yeah that is probably fine for most apps, including the OP.

This is also super nit-picky but also worth mentioning that if you were to expand this by using a sub, it's not the low pass you need to worry about because almost all powered subs for past 10+ years have built in crossover for this so even if you send it a full range signal, it will only reproduce below 80, 100, 120, whatever you select it as. My concern was more that your mains would ALSO be reproducing those lows which could cause weird bass response in the room (this is kinda how cardoid subs work actually), but if you used the graphic on the mains to do a faux-high pass, it would probably be enough to deal with it. Anyway, I recognize that's getting borderline former fmbd (and also I could be just completely wrong) so apologies for even bringing it up.

In the real world a more legit concern I thought of that would be a potential drawback for using powered mixer is that a lot of them don't have separate unpowered main outputs so that makes getting the signal to an additional PA a bit of an issue.

Most small Mid/high (top) cabs don't really extend down far enough to interfere with a sub too bad, unless you are spending a lot on nice Mid/High cabs. On my old Yamaha mixer, the graphic only effects the amplified main outs, and I run the sub off the "monitor" outs which are basically just the unamplified line level output of the mixers 2 buss. I actually do cut a little low on that graphic to let the sub lift more of the lows and not push the terrible little wedge speakers too hard. Works well. Not a HiFi solution, but works. powered speakers and a powered sub with a regular mixer would get you the same result, and you could utilize something like an Ashley 2way xover or something to really nerd out about those bong rattling bass notes. The little powered mixer works for me so far though.

Cardioid subs are a fun thing to play with though. I would have used them more when It wasn't so cumbersome and space consuming to set up.

This probably doesn't help, but I saw S U R V I V E a few years ago and they used stacks of SUNN amps on stage. Not sure what combo of their gear was direct-in to the PA and what synths went into the on-stage amps. It sounded heavy as fuck, though.
