/vr/ - Retro Games

I just got this Trinitron from a guy on Gumtree. It has had the sticker on the back with the model number removed, and it came with no remote.

I have noticed since playing my SNES with it that the picture size needs adjusting, but it seems like this is not possible without a remote. Some people in various threads I have been reading have said you can use other Sony remotes or universal remotes to get around this issue, but I am not sure how true this is.

Can anyone possibly identify a model (or one close enough) that I could purchase the remote for that should work on this TV? I know very little about CRTs, so any help with me greatly appreciated.
