Kenwood sperates - help needed

[Faust66]

I have a Kenwood Seperates system... it's an old 'un but I like it!

The only problem I have is that I lost my remote control in a house move. The only serial number I can find is on the amp, and it's DP M85.

I appreciate that this is a bit of a long shot, but does anyone know which remote (i.e. the serial number) I need to replace the lost unit? Failing that, can anyone suggest a replacement universal type remote that will be suitable?

Thanks in advance.
