I've got a GK 800RB that needs some work. The head is working but after opening it up it looks like it may have had some heat issues in the past. I live in Redondo Beach and the GK site lists AMPWERX REPAIR in Long Beach as the nearest Service Center. The AMPWERX website doesn't say anything about them being a GK Service Center. Anybody had their gear worked on by these guys? Also, how hard is it to find the stock side covers? This one has the the full rack mount sides on it. How about replacement feet? Does GK sell them? Hey! Thanks alot!
