Using universal remote control with Line Magnetic amp

Thank you for your replies.
I am in South Africa. I imported the amp from Cattylink 2 years ago and they don't seem to exist anymore. I never regretted using them, btw. Got the amp for $2100 shipping included, great service, and the salesman, a mr. Lee, sent me some of his personal used valves (the small ones) for a bit of rolling. The amp is driving Westminster Royal SEs, and I couldn't be happier.

Anyway, I finally found the LM agents here. Thanks for your suggestions.

I have a LM 518ia with remote. Inside the remote the board has the following:

LM-YK-IA, PCB
VER: A
2010-04-20

Hope this helps

Outside the unit on it’s face it has the following:

Line Magnetic
Remote Control Unit
LM-02

Thank you for your effort, ekimg. I will pass the codes on to the LM agents here in South Africa (I cannot make sense out of them myself).Otherwise I will just have to order a new one - but one'd expect that it would be possible to use a universal remote on LM components, I'm sure.

Good luck. In case you forgot the remote only has volume up/down and mute. No other functions.
