Re: k6100 spot killer TPS98's

I found the following in the 6100 FAQ Guide:

"Very infrequently, you may have problems with some other transistors
in the X/Y amp section of
the board. Most of the other transistors that populate the deflection
board (Q600-602, 700-702)
are type TPS98 and are not easily found anymore. The good news is that
TPS98 is equivalent to
the PN3569 and the ECG or NTE 194. All Electronics (800-826-5432)
usually has PN3569
transistors in stock."

Mouser has them in stock:

http://www.mouser.com/ProductDetail/Central-Semiconductor/PN3569/?qs=sGAEpiMZZMsTKkj12KWLXuW5oDYpP%252bzxlnbYa3cIV1Y%3d

Though I would check the pin outs and make sure they are correct.

I hope that helps!

Thanks
