any opinions - they look overpriced for the spec.

Hey everyone!
My KORG iS50 has a volume issue where the internal speakers are only acceptable above ~50% on the master slider. What's worse is that the headphone (phones out) and line outputs are extremely quiet, even at max volume. Both left and right channels are equally affected.
Here's what I've checked:
Voltages: Vcc to DAC section measures ~5V, MUSB (mute pin on the DAC) measures ~4.xxv, and the 2 op-amps show ~9V
Master Volume Slider: Resistance ranges from single-digit Ω to ~11kΩ (seems functional).
Visual Inspection: Capacitors on the main/speaker... -
Has anybody tested this product? Posting this question on a Facebook tech group I'm in got a few responses like "that kind of thing corrodes the tips" and "just using normal solder paste is much better" so I'm not looking for generic responses like that, but rather, does anybody know for certain whether this exact product is good or bad for soldering iron tips?

I've just been repairing some (very) old speakers with a loud hum that occurred as soon as you powered them on regardless if any actual audio is played through them. I work in a School so it's 99% likey that the Teachers have hardly ever turned the power off on them for well over 10+ years.
As you can see the top large capacitor on the right has a bulge on the top so defincately needs replacing. As the one next to it is exactly the same capacity and voltage I planned to replace them both.
What is your advice/opinion on whether or not on old(er)... -
I've got a bunch of Poly VVX-250 VOIP phones that work fine as kind as long as they are plugged into the wall wart. Recently I got around to install a couple of TP-Link 5 port POE switches that are added to the existing plain Jane 24 port unmanaged switch. Great!!! Finally I am able to ditch the wall warts from these phones making more space on the desk, plus I am gaining some badly needed power outlets. So I thought.
Plugged in the first VVX-250 into the POE switch, booted up no problem. Plugged in the other Poly phones and they start to boot anywhere from 5 to 15 seconds,...11-25-2023, 10:46 AM -
Back in 2020 i bought a (2nd hand) compact ATX psu to replace my current one. My PC case only fits very short ATX power supplies so i didn't really have the choice of buying a decent 80Plus unit. The current unit is a modded YoungYear unit that i made a thread about a while ago:
A "nice" YoungYear unit? - Badcaps
The "new" unit is a KDM-M6480 480W psu, the 480W number is a typical KDM bullshit claim of course, but the 24A rating on the 12V rail seemed reasonable and the "Active PFC" claim gave me a bit of hope that this was going to be decent-ish....
