Sorry for digging this up from the grave, but trying to see what it takes to swap in a P-206 UHB from a P-204 UH, the former is for sale w/ speakers and amp, how much of that do I need to swap in? Just the amp?
Surprised I haven't seen this yet, but any talk of a poor oil pickup design? When mine went the shop recommended going to Killer B and so far so good (knock on wood). Updated to VF52 at the same time though.
