Default Help! Tannoy AMS 8 A active monitors schematics wanted

I bought a pair of these s/h. Since they are 10 or so year old, i would like to do some overhaul on the electronics.

I was advised by a Tannoy technical supervisor from UK to contact Tannoy North America to find a schematic of Tannoys AMS8 A. However they (Tannoyna) cannot provide me details since they say it's the Europe version!

Tannoy UK kindly provided me only schematics for the amp section in the first place but they look different than what is on my boards. My version of amplifier in AMS 8A does not use IRF output transitors but complimentary Motorola MJ15003/MJ15004 as can be seen in the picture attached. Also i see differences in psu values. My model is clearly labbelled as AMS8 A EUROPE on the back.

Could someone help me locating the schematics for the electronics ( amp + crossover) for these boards ?
Many thanks in advance!
