I recently purchased a CT-7000. One of the items I always wanted to have. I knew about one of the problems with this model: The heat generated by the TIP transistors in the powersupply. The model I bought has undergone a modifcation. The TIP41C's are moved to the chassis. Now part of the chassis functions as a heat sink. Temperature is well under control now. The attached pictures shows the tuner with the mod (1) and an original model (2). I would like to hear your opinion about this modification.
