Bought from Cashconverters a year ago,after initial boot up found it didn't switch from green to red without a nice big echoy fart but red to green ok.

Took amp to a local tech but he couldn't sort the prob.

I've done a bias upgrade on a dsl50 and was succesful so if you have any diy ideas that I could try,please feel free to send.

Ps...I hearby exhonerate you from any faults that may occur.

Kind regards,

Paul.

Ps...I've read the RL1 in a tsl has fixed a similar issue.
