This is probably a well-worn question, but I've yet to find the answer anywhere online.

The preamp in my circa 1993 12-string Legend 1756 has packed up. This has been tested and confirmed by our local guitar fixer, though he didn't have a 'keeping it as original as possible' solution and referred me to the internet.

Is there a perhaps later direct replacement for the old OP-24 preamp? The guitar is otherwise still flawless, plays beautifully, and I neither want to replace it nor cut it about to fit a different kind of preamp. This has to be a common problem as these 1990s electronics start to fail, so I'm sure there is an answer.

And before anyone suggests it, I did email Ovation two weeks ago about this but have had no reponse. I'd also like to sort it fairly soon as I plan to come out of retirement and start gigging again soon.

If you have not received an answer to your email in two weeks, you probably never will.
Either send another email or call them.

I would call them. 1-800-552-4681

I just looked on eBay... I don't see any OP-24 preamps for sale.

Still digging for info, I have found a guitar specialist who is selling OP-24+ preamps. It looks the same shape, but no dimensions given. And anyway, can these be used as a straight swap for the older OP-24? Or is it a not-quite-straight swap but possible with a bit of the right knowledge. Is there anyone on here who has done this swap, or knows anything about it?

I think that the OP24 and the OP-24+ face-plates are the same size.
But the OP-24+ preamps that I have seen have an battery box in the side, and the OP24 has a battery box inside the bowl.
But it you are handy with at soldering iron, that should not be a problem.
Also, the OP-24+ might be a little bit longer.
You can make the hole a little bigger, but you cannot make the hole smaller.

Once again... Call Ovation, they might have an OP24.

In case you didn't go there... I sent your question to the BFLG.
And it looks like the OP24 and OP-24+ are not a direct swap-out.

Thanks for that. It clears up the theory about swapping in an OP-24+...and has saved me from spending over 100 pounds on something that could be a real pain to fit, and may well be beyond my capabilities.
I'll try Ovation again. Fingers crossed...
