It is entirely possible that Kortek used the same board for both models with some component tweaks. They did this for the KT-3414DF, for example (uses KT-2914 chassis).
Yeah, after doing some searching on the KT-2182, I found that what you say is probably the case. In fact, after giving it some thought I remembered having a Sharp 27" in a Big Buck Hunter II cab. I checked my records and in fact it was just a KT-2182 as well. I guess it wasn't standard practice to put a 2182 into a PGA Tour Cab but it should work non the less.
With that in mind.. Any thoughts on the clicking noise? I'll test the HOT tonight, I'm hoping that's all it is.
