Help Troubleshooting Super Sonic 22 - Crackling, Strange Reverb Knob Behavior

I've got a Super Sonic 22 combo that's got some issues that I hope you can help me suss out. It makes some pretty bad crackling/farty distortion sound as soon as it gets above a certain, not very loud, level. The reverb knob causes the overall volume to drop as you turn the reverb knob up. When the reverb knob bottoms out, the amp starts squealing. Tapping on any of the knobs causes a scratching sound, as does tapping on the power tubes.

I tried using Gemini to help me debug this, but it's sprinkled enough obviously erroneous info in the chat that I don't trust it. Regardless, some things it directed me to try were:

Patching the Effect Send directly to the Effect Return (didn't change anything)

Swapping the positions of the power tubes (didn't change anything)

Reseating all the tubes (didn't change anything)

I don't have a separate set of power tubes to swap in, so I haven't tried new ones.

Any ideas on what could be the issue? Faulty tube socket maybe?

I got this amp couple months ago in a lot of other gear, and it's been like this as long as I've owned it, so I can't speak to how/when the problem may have started.

Mid-Life Pivot Back Into Software Development?

About 25 years ago, I got a Comp Sci degree and worked a couple years as a developer, then the dotcom bubble hit us and I decided to take the opportunity to explore my creative side and eventually wound up working in game dev (audio) for a long time. Well, now that that industry has shit the bed, I’m looking at what my options are and am wondering if pivoting back to software is a viable path.

I have no delusions about my dev skills being anything other than extremely rusty or my being able to get in anywhere above a junior role. That’s fine.

I’ve been advised by someone in CS research that, if I want to do this, I would not only have to re-learn coding, but also get very comfortable with directing an AI bot to handle most of the code. That’s fine, too.

What I’m wondering is if there’s any point in even trying. I know things are tough out there, but I have a hard time believing it’s as bad as game audio (which was tough even in good times). Is there space out there for someone with the maturity of a senior but the skills of a noob?

If it matters, I don’t even use weed and could easily get a clearance if somebody was willing to sponsor me.

6G2 Brownface Princeton as First DIY Guitar Amp Build? Or Go More Simple w/ 5F2 Tweed Princeton?

I'm kicking around the idea of building a DIY guitar amp and I'm trying to decide between a 6G2 and a 5F2. I'm more interested in having something that produces the sound of a 6G2, but I also don't want to get in over my head. I know the 6G2 is still relatively simple, but I kinda don't know what I don't know, so I'm looking for your input. Some info:

My soldering skills are passable. It's mostly been cable assembly rather than components, but I can get by. I at least know what good soldering and wiring should look like.

I know next to nothing about how electronics work. I can read a schematic and identify parts and how they're connected, but am clueless as to why 95% of it's there or what it's actually doing.

I'm only interested in building an amp head, not a combo.

I have zero interest in replicating the original aesthetics of either of these amps. I would build this inside of an old radio or other shell of more-than-ample size. If I can salvage components, great, but I'm not banking on that and am not looking to hot rod an existing circuit.

I'd most likely source the parts myself from a list rather than buying a pre-made kit. Partly to (hopefully) save money. Partly because I haven't found a 6G2 kit (there are 6G3 kits).

Thoughts? Am I making too much out of this?

What Is This Tele Tailpiece?

Saw a band last night one of the guitar players had a Tele with a tailpiece I’d never seen before and couldn’t find on the googles. I didn’t get a chance to ask him what it was, so I turn to you all.

What is it and is it stock or aftermarket? It kind of looks like a T-bender or a detuner, but for every string instead of just one or two.

I've got a pile of surplus equipment that I'm trying to dispose of and among the lot are a couple of Yealink CP965 conference room phones. I usually just do a factory reset before I send things off for resale/disposal, but I'm seeing these described on ebay as "unlocked" and I'm trying to figure out exactly what that means in this context. I am completely unfamiliar with these units and the manual isn't helping. Does "unlocked" just mean "able to be logged into" (in which case a factory reset does the trick) or is this like cell phones where the hardware can be locked to a specific owner account or service provider? (in which case, they're just trash)

Thanks in advance.

(For Rule #8, I am not trying to sell these to anybody here)

A guy nearby took the chassis and transformers from an old Muzak-style radio receiver and replaced the rest of the guts with a 5F2A circuit with switchable 4 & 8 ohm outputs. Now he's looking to sell it for $275.

I haven't heard it yet, but the photos of the inside show the assembly work to be passable. Not amazing, but this won't be leaving the house, so it doesn't need to be especially robust.

I normally play through an AC15 head into a 2x12 loaded with a Greenback and a V30. I like the Vox, but sometimes I'm in the mood for something a bit more honky.

Anybody wanna talk me into or out of this? $275 seems like short-ish money if it's functional and roughly what it would cost to get an unassembled kit on ebay.
