Yamaha P7000S rare transistors

[hostname]

Hi all,

A few days ago, I purchased a dead Yamaha P7000s amp and after a quick look inside, I discovered that few 2SA1993E transistors are missing from SMPS board... seems that these transistors are very old or unpopular, I can't find where to buy them... So I'm looking for a good suggestion from you guys, which replacement I should use??

Thanks for advices!

Yamaha service, (certainly in the UK), are very helpful, drop them a email and they might be able to help out. The amp is certainly still in production, we had twenty through here for a client last week.
