Soundcraftsman MA5002A

" They really do have the potential of being great tube amps ". Do not understand what this means., as they are Class H, high powered ss amps..…..

Boxer, that's a fine point. Is there anyone qualified specifically to Soundcraftsman anymore? That would be great info & some assurance that it would be a worthwhile purchase

Mr Decible is absolutely correct. I was mixing "Soundcraftsman 500" up with "Radio Craftsman 500". 
Vista,
I don't know anything about that amp other than a stereo store (Electronic Sound) near me in the 70's sold them. They have been out of business for some time but if you live in Michigan there is a store called Misfitz Audio in Grand Rapids that could check it out for you. 

Thank you boxer
