If you want to try making a visual match, you could see if it looks like any of the remotes here, but remember, just because remotes look the same doesn't mean that they will send the same signals...

Regardless, this is mostly academic because we have narrowed it down to to codes that will probably work this set, with one being more likely than the other. So if you were to get a JP1 cable, you could load them and try them yourself. With a JP1 cable, you would also have the ability to cature the signals yourself, so even if none of the existing Akai upgrades work your set, you could create a new one.

If you don't want to buy a JP1 cable, you could send me your URC_8811 and I'll load the codes into it, just cover the round trip postage.
