I found a 'empty' 4x12 cab on OfferUp for free, went and picked up the cab, got home and found within it wasn't actually empty!

Found the following:
Line 6 Celestion C12E-50 4Ohm 50w
Two Team Sonic C30L34 4Ohm 40-120w
FST 87-450-80 8Ohm 30w

The FST I found the info on reverb, it's hard to read much more than 8Ohm on the speaker itself.

As you can see in the picture, the wiring is a mess and makes no wonder the guy thought it was empty, if the speakers are even any good.

I've been trying to work out how I can get this cab down to at least 8Ohm for one head and possibly use a toggle switch to flip the wiring to get it down to 4Ohm for a different head. I'd be happy to get it to 8Ohm, but my best thought upon it is I would likely be able to get it down to 10Ohm if connected series parallel.

Is there another way to wire this using all speakers or should I just use two 4Ohm in series?

Just need to box this one up in the morning, spent about 6 hours on it.
Was fun and a little challenging given the through holes are slightly smaller than the GreenBean2019, but sounds pretty cool, can't wait to get it in it's 1590A and put those mini Oxblood knobs on.

It's alive!!
I had to sub a film cap for a ceramic, but it sounds fine as far as I can tell on my little test bench amp plucking a few strings.

In my quest to find a TQ2-L-4.5/5v in stock, I ordered the wrong part and have 5 of these, also paid a little over $3 each, $25 on amazon.

Are these useful in any way for pedals, amp project or anything general use that would be interesting and useful to build?

I've got a little time to return them, but figured I'd ask before I did.
I know they likely aren't useful in the VFE bulls because they aren't latching, maybe they could make for something though...?

So I ordered a 10M ohm from small-bear and on my Klein MM700 it's reading at around 6.5M ohm.
Resistor is supposed to be a 1%, but the reading is showing it far far under that spec, use or contact small-bear over it?

I've already soldered it in, but having second thoughts while I wait on the rest of the parts to arrive from tayda that small-bear didn't have or were out of.

In the PDF it says:
"In the Notes section I suggest a mod for the Treble band distortion which replaces R11 with 4k7 and C14  with 470pF. I strongly urge you to use this mod (or at least socket both components and compare them yourself).The 4k7 and 470pF are listed in the Shopping List above."

Does this mean the parts in the shopping list are already switched to the mod or I should order 1 more?
The schematic shows the part values, but I'm not seeing any socket designations for R11 or C14 or I am becoming blind. 😂
