Thunderbrick, I'll be honest I don't know what the output is on them. They were my brothers and he passed away. I want to sell them toward his child's inheritance.
S Clark, I just don't think they have that value. I looked up used value on the 2 you mention and the cheaper of the 2 has a value of $2300. I used to own one of them and they are nice sounding in stereo form as well as mono. I've listened to them at my brothers a number of times and they are sweet.
Thanks,
Mark
