Subject: [TechAssist] TT2168LS-YB11 HZ Output Transistor


Hello:
I have a customer set (Sanyo model DS25204 / Chassis DS25204-00) in my shop 
which has a shorted TT2168LS-YB11 HZ Output Transistor, location Q402.  The 
closest service data (As far as I know) for this set is for the Sanyo DS25320 
(HSPF # 4801) which uses a 2SD2578YB for the HZ Output.  The 2SD2578YB is 
physically much larger than the TT2168LS-YB11 used in my customers set.

I havent' been able to find a sub for the TT2168LS-YB11, and I have only 
located 
the exact # at Tritronics. Also, I have not been able to locate a data sheet 
for 
the TT2168LS-YB11.  Has anyone come up with a sub for the TT2168LS-YB11?  Also 
- 
I was wondering, since the related model uses a 2SD2578YB, how about drilling a 
mounting hole higher up on the heat sink and using a 2SD2578YB instead?  By the 
way, I have used many 2SD2578s over the years, but not ones with the YB suffix. 
Haven't been able to find a data sheet on the YB variation. Anyone know what 
the 
YB means?

Thanks!
