MERIDIAN: M2 active speakers – problems re bringing them back up to spec

Hi, I have a pair of Meridian M2 active speakers I have owned since new in 1983 which I wish to upgrade. The original tweeters have been replaced with a new / secondhand pair of Kef speakers. I had intended to remove the amps from the back of the speakers to send them to the U.K Meridian Repair Shop however sadly they have just closed.

I will now have to find a local technician and explain what is required. As the amps are now over 30 years old I am sure the caps could be upgraded but will need advice on this. I have also heard of wiring upgrades such as running separate power cords to each of the amps (two amps per speakers) Any advice on upgrading the M2's would be appreciated

Cheers / Phil
