Hello all, I have this old Cambridge Audio amp set and I basically know nothing about it. The model for the preamp is A75 and the power is C75. I think that they could have potential but first I need to know a little bit more about them, so this is a call for help from anyone out there who may know more than I do. I would especially like to know info about the output so I could match some speakers and really be able to listen to the set. Please, any help is welcome. Thanks
