I am now replacing the original Toshiba 2SC2652 transistors with Motorola MRF-448 Matched Quads
**UPDATE:** I have found that the transistors made by "Advanced Semiconductor Incorporated" will NOT work in the FL-7000. These transistors appears to have the wrong capacitance. I was working with ASI to correct the problem, however after 3 sets of transistors they sent me, none performed like the original Toshiba transistors.
A picture of the OEM Toshiba transistors is shown below (bottom picture below).
