Restoring a 70's 810

...but why?
That's gonna be a huge pita as far as wiring/ohms. Well, maybe be not... But why?
Why? I think it's great solution for portability. One cab for the bedroom or coffee shop gig. Two cabs for your rehearsal area and up to four cabs for a big gig. This is basically what an Ampeg 810 is, right?
It is technically 4, 2x10 enclosures. However the 810's use 32 ohm speakers so each "pair" registers 16 ohms, with each half of the 410 being 8 ohms... Put 2, 8 Ohm 410's together and you get a total 4 ohm load.
So (I Think) if you have 4 - 16 Ohm cabs it may be difficult using just 1 since I don't know of many bass heads that operate at 16 Ohms. You may be able to work it out with a series / paralell box of some sort.. maybe?
I could be way off..... and regardless I am going to get you the dimensions of the middle sections that you requested. I am all for projects and fully encourage going for it... but I think that may be what DeathbyDoom was referring to.

I plan to buy a Reeves in the future, which can run 8, 4, or 2 ohms. I'm thinking of wiring each cab 8 ohms. To run all 4 cabs it would have to go down to 2 ohms.
Any high power solid state head should work fine from 16 to 4 ohms - but personally, I am not carrying four separate cabs to "the big gig".
That would work. I think 2 Ohm heads are where it's at! All of my gig-rigs can go to 2. Never hurts to be able to add more speakers. I didn't want to start tell you what kind of amps to buy or how to plan your project. May I suggest fliptops for ampeg parts / harware and penn-elcom for everything else: corners, extrusions, feet, wheels.... literally EVERYTHING.
Thanks for following, Ill get those measurements!
That's ok, I would only build for myself
I know I have seen someone post photos of their 4x SVT210AV rig - I don't remember who - or what head they were using though.
Yeah, Ive seen that too. Those cabs have different speakers than the 810. But, so would the ones I would use.
Sub'd. I have a fridge that is in bad need of similar TLC. Thanks for posting your progress pics!

After walking my puppies this morning, I opened the garage to check on how last night's coat of urethane cured. To my surprise, as I rounded the corner of my impromptu paint booth of tarps I could see something laying on the surface of the cab... ***? A Leaf? Debris kicked up from the wind?
No. - A gigantic female anopheles mosquito. After removing it, I proceeded to pull each leg out of the finish. Good thing I've got a coat left to go on the back... the Urethane should fill the Leg-Marks good enough... A new level of mosquito induced irritation for sure.
At least I should be able to finish getting the hardware on this weekend after I get the final coat of clear on the back.
2 sides left to go!
