NCD: Peavey 430A 412 cabinet

Leon at Otto's cut roughly 0.5mm off of each edge of the board now and it fits fine, is just slightly smaller than the original board (we peeled back the tolex on the back to get an accurate measurement). Test-fitted fine, but as it turns out the original board - which was actually particle board, not MDF - was designed to bow when tightened to give a tight fit. MDF doesn't bend like that so I will need to sand down the centre post a bit to enable the board to go on flat, and then put some soft packing material over the end of the post so that when tightened up everything is tight and rattle-free.

Tolex is on its way via Express Post from Queensland.

Next job will be to remove the four speakers and wiring so that I can lay the cab on its face and safely sand the post down with a belt sander without damaging the speakers. Then I will text fit the board again and make sure it is all tight before installing the Vintage 30s from my other cab. Then it will be time to add the tolex and lastly to install the new jack bezel and rewire the cab. Hopefully this time next week it will be all finished.

Good work! Lots of details!
 
Making progress DD. Good to hear.

I wound up deciding to alter my original plan for my Behringer in favor of having the most flexible options in the future.
Since the cab is closed back MDF, I wanted to make installing or servicing the speaker wires way easier than trying to solder in all the wires and mount the speakers all hard wired with switch/jackplate installed from the front and only having access through handle and jack plate holes.

I went ahead and soldered some female blade type ends on 4 new wires to make the speaker to speaker connections, then soldered these same type ends onto the 4 wires off the PCB switch plate. Mounted the two bottom speakers with the wires attached, then mounted the top pair and connected the wires from the bottom speakers to the + and - tangs on each top speaker. Put the jack wires on the appropriate top speaker tangs and checked my Ohms before screwing the Jack plate tight.

Plugged my Ashdown bass amp in and got my SG and all sounded good so far.

As for my flexibility, if I should decide to sell these speakers including cab, it will be working as it did with OEM jacks and switch. Or if I want to switch these speakers into a different cab and run a straight up single input jack 16 ohm Series parallel type wiring scheme, it is easy to swap the wires around and not have to de-solder then re-solder or cut wires etc.
 
The actual Behringer front loading is not the worst. It actually went smoothly and I likely could have soldered smoothly as well.

Now the Mesa 4x10 Road Ready I have is a whole other monster as my first front loaded and hardest to wire up affair to date.
Try keeping all the wires straight and soldering etc when there is barely enough wire to get the speakers far enough out the front to flip em over. Compound that with the cab being sound foam lined and not wanting to catch that stuff on fire etc. All said, this cab is still one of the nicest sounding bass cabs I ever used. Just a pain to service unless one does like I did with the Behringer and have detachable wiring.

I will be inside that one soon enough, and you will see pics of all I speak. Cab is basically an ANVIL road case with speakers in it, so you know how valuable that solid aspect of it can be. Great caster wheels on it too. The Behringer ones suck and will get new ones ASAP.

what is " stubby of VB?"

Very handy in hot weather:

although, I've also heard many Australians just call a small beer a stubby too:

I've removed the centre post so that I can test fit the rear panel properly. The panel is slightly thicker at 16mm than the original 5/8" but it's as close as I'll get here in Australia, where we have had the metric system since the 1970s. There is a slight lip that you can feel but not too obvious. Note that Peavey didn't drill the top centre screw hole in the centre. We probably could have fixed that but didn't notice before matching the original. I might fix that before fitting the tolex. Tolex also arrived today, looks fine, will get to it later. The speakers in the Peavey cab have these irritating Torx screws that seem to be a loose T25. I have some boxes to put each speaker in and will try removing them later. I have taken the centre post out for now as it needs to be cut down a little, but it will go back in eventually. I used some tape and a 1mm bit in my Tamiya Handy Drill to fit the new bezel, using half of the screws from the old one. Here are some photos (note the part description on the 430A centre post):

The worst gear I've ever bought are Marshall MG amps and Behringer pedals - some folks seem to like them, but not my cup of tea, oh sorry, stubby of VB.

I think you got mixed up as to who owns the Behringer cab, that's not mine.

I might be Aussie but I don't like VB. I'm more of a Heineken guy, or Coopers Pale Ale if going for a local beer.
 
^ Coopers is good. They sell that all over Asia, so drink the varieties quite often.

Have you finished yet, Dave?
 
Well, I've made a monumental fuckup on this. I just worked out last night that I should have made it in 12mm MDF. It's too thick. With the fabric stripped off the original back panel it measures more like 12mm, which is apparently what Marshall use for their backboards (12mm MDF, not 15mm). The board would stick out so far with the covering added that it would most likely strip the expensive tolex off in short order. I wish I worked this out the night before as I've just been down that way and it is roughly a 100km round trip from my house.

At the moment I kind of feel a bit like these idiots
