I am close to finishing building a K1 and am presently about to install the two T-220 power transistors, Q6 and Q7. The K1 assembly instructions indicate that Q6 (transmit driver) is a 2SC2166 and is labeled C-2166. My T-220 package is labeled C-5739. Is it OK to use the transistor that came with my kit? Are they electrically the same? Also, according to the instructions (pg. 43), I am suppose to mount a "self-adhesive thermal pad" under Q6 and Q7. I did not receive any thermal pads with my kit. As Q6 is a plastic T-220 package, I don't understand why I need a thermal pad under it. Thanks in advance for any help/suggestions.
