OK, new question...
Finally had a chance to play with the amp. I have an old Compaq 19v laptop power supply and the hole in the centre is too small so I can't fit it into the power jack.
Grabbed an 18v laptop power supply from an HP laptop I have, and the plug is too big.
Sigh... ended up testing with a 12v adapter for LED lights, 12v3A, and got some decent volume out of the speakers.
Question is, the eBay listing says standard 5.5mm power jack, what are the dimensions of a standard 5.5mm jack? like length and hole size?
I think my best bets are to either (A) cut the end off the PSU and solder on a new one or (B) solder a new jack onto the amp board, except I have no idea what size that Compaq plug is.... well, 4.8mm but not sure the hole size.
Figure when I get the caps online I'll grab one.
Funny story about that though... few years back I bought a few audio kits off eBay, then moved a few times and just never used them and lost them. Found them today, probably over 100 caps, almost all nichicon and rubycon, and a small handful of tiny 100uf and 220uf Chongs?
EDIT - Compaq e500 PSU - 4.8mm OD x 7.1mm ID. Not finding any jacks on DigiKey to solder to the board so, I guess, male plug, 5.5mm OD... what's the ID and length?

Well... assuming it's a 5.5mm x 2.5mm similar to a Toshiba laptop battery... about $5 for a cable from Digikey, or $10 for a new PSU from eBay from the USA (cheaper to order from the USA than from Canada... go figure).
Just need to confirm if a "standard" 5.5mm jack is 5.5mm OD x 2.5mm ID. I'd ask the seller but, eBay China so, from past experience, the response won't be overly helpful.

That Compaq psu plug is... related to a black hole, perhaps? Not sure how else the inner diameter (hence the "ID") is larger than the outside diameter
"5.5mm DC jack" usually come in two standard flavors, to the best of my knowledge - 5.5x2.1mm (as in guitar stompboxes) and 5.5x2.5mm (a bit less often seen, in my experience - on "medium power" stuff though, like computer audio interfaces).

Oops.... 4.1mm OD 1.7mm ID.
Hmm... I guess I'll have to well, guess, between 2.1 and 2.5... always great when they say a standard 5.5mm jack and there are 2 options.
EDIT - 12v Adapter for my LED strip fit, was lucky enough to find the same one on eBay and they listed the plug size... 5.5mm x 2.1mm.

Well... few people said they used a standard laptop power supply... spent an hour on eBay looking an laptops don't seem to have as 5.5 x 2.1, pretty much all 5.5 x 2.5.
Weird they'd use a standard adapter plug size, but then recommend a 19-24v power source for it.
Luckily, DigiKey order I placed (at 1am) didn't ship and was able to add a new 6' long cable. Had to go through a lot of datasheets because almost all were rated 12v, but found one rated 36v 3A, and my PSU is 19v 3.1A so I think I should be ok. About $4.90CAD so, open the PSU I have, solder in the new cable and good to go hopefully.
$4.90 was cheaper than a new PSU for sure.
Grabbed a bunch of caps, for this amp and the guitar amp project as well. Annoyingly, those kits I grabbed years ago, over 100 caps, most Nichicon/Rubycon... and I swear, not 1 single cap matched what I needed for either project. :S

Replacing Ebay Sanyo for Ebay Nichicon/Rubycon, "unfortunately" values were wrong
You are? or me?
Kits I bought were eBay but from Canada... not China, so probably legit not fakes. Just a case of if I need a 47uf I had a 4.7uf, I needed 100uf and had one but volt too low, etc...
Third place after china and hong kong, I knew dutch money warehouses stocking drugdollars were in Canada for no good reason, Canada is Eldorado when you do not speak chinese and do want to finance terror or earn an illegal buck, or so it seems.
