Early model 200's had some issues I've heard, but mine was the last board number made, bought it off the shelf (229.00 on sale)and sent it to cobra for the free tech updates. (No Cost but shipping)
I was unfamiliar with the design so when I got it back, (I used it with good reports for about 6 months), then had the 2SC2879 mod done to it, Replace power cables, and a mod to the power circuit to the 2879s and a cooling fan installed.
Stock it would do about 80 watts in reality... now I get a VERY clean, not overdriven 170 watts with great audio.
I think most of the problems people had with these radios was from turning up the power without beefing up the cooling for the finals. Zero airflow and the factory heatsink that is thick enough but it has NO air surface to speak of... so the heat just stays there.
These are great radios if a tech that knows and understands them works on them....
