1972 Vintage tweed 2x12 - speaker replacement

[Many Mountains]

Hi All - long time reader, first time poster here.

TL;DR - What ohm speakers would have originally been in the Vintage 212?

I have one of the all-tube Vintage 212 combos (I think 1972). I bought it used and it does't sound great. The the tubes seem to work fine (and I had a knowledgable friend test them).But it sounds weak, trebly, undefined, no low end. The speakers are mismatched (one is square back and one round). I'd like to switch out the speakers to see if one of those is the issue. However, I don't know if either of those are original, though the square back looks much older. Were these were 8ohm speaker wired in parallel for a 16ohm load?

FYI, I purchased the amp, a guitar and a stand for $100. I quickly sold the guitar for $75. So, I have only $25 invested in this amp. I would love to get it rocking!

They probably were two 8 ohm speakers wired in parallel which gives you a 4 ohm load, not 16. According to the manual, which you can find on Peavey's website under Archived Manuals, you can run on a 2, 4, or 8 ohm load, but it was set up a 4 ohm at 110 watts configuration.

As to square or round magnets it doesn't much matter if they have the same spec's. If they are working I would work on getting the amp serviced and running correctly before spending money on speakers.

You need to clean all the jacks, pots, switches, connections with contact cleaner. Good chance there are some electrolytic capacitors that need changed out (personally, I would change them all). Test any of those large power resistors in the power section and replace them if necessary. Take a good look at the solder joints, especially those in areas that get warm/hot like the tube sockets. Get the amp running good and it will be easier to select speakers for it.

Thank you very much for the info! You gave me a good place to get started on reviving this amp.
Here is a picture of the two speakers in question

Thanks again for the info. I was able to find the manual. A follow-up question - since I think the speakers may be a problem, and the amp can handle a variety of loads, would it be ok to test on speaker at a time ? That would be an 8ohm load, and I wouldn't play it loudly.

Thanks in advance!

You should be okay. You may very well find that one or both sound terrible. While you're working with those speakers check the spiders on the cones. Sometimes the glue starts failing and they look fine but make noise. That's easily fixed. And you can also check for cone rub but you will probably hear that when you test them.
