No, I can't. It is unusual to find any remote than accepts all codes. You might try calling the Rega distributor. Ask which remote their's is based on. Most remotes for companies such as Rega are not proprietary to Rega but are taken from other companies and Rega tacks on their own codes for particular functions. But you may not be able to have all codes in one universal. That's just kinda life in the land of universal remotes.
If you look on Rega's site you'll find the Solar remote manual (under Products, then Accessories)which contains all the codes, so youshould eb able to program them into your learning remote.
The Solar remote speaks RC5 which is just about the most common language for remote controls. Any learning remote, such as a Pronto should be able to handle this.
The pronto JFYI, can be a pain. I have a Mosaic, and it carried more codes for my system, and was a bit easier to have it learn the functions it did not know. I tried the Pronto on two seperate occasions, the last being last xmas (my wife bought it for me) cant remember model number, but it was a 2000.00 remote at the time, color screen etc. and even through their website there were certain functions, as well as my Rotel DVD player that it would not accomodate. Maybe things have changed by now, but for me, it was just easier to stick with the Mosaic.
