for a list of compatible IR receivers.

If you look for a compatible IR receiver: I found this kit to be compatible when I bought it years ago (though there’s always the risk they change the contents of the kit, so if you purchase one, please make sure you can return it just in case):

Alternatively, the "Manta TR1 Only“ offer here is also an option that is known to work and available (and Twisted Melon so far always let me know whenever they change the product, so I can make adjustments in time):
