I bought a used 80's 800RB 3-4 years ago. When I bought it, there were some holes drilled on the side of the amp. The owner told me that he did those holes to be able to rackmount it. I didn't care about that problem 3-4 years ago but know, I really want to rackmount it.
So, considering the holes the owner drilled in the head, is it possible to rackmount my 800rb with the new rack ears (the ones on sale on the GK website) or I need to buy the older ones, which are harder to find and cost more?
