Need a "D2578" Horizontal Deflection Transistor for an RCA model #27628.

Please, I need a "D2578" Horizontal Deflection Transistor for an RCA model #27628. I think the equivelency is a "2SD2578 sanyo" (not sure). In any case, I just need "one" and am willing to pay $25. AND with integrity if this part does fix my TV, I'll be sending you another $25. as vested interest in my pursuit. I am also willing to accept a known good "used" part too. thanks, mark, [email protected] or 469-644-0330
