Looking for 2sb681 + 2sd551 (or analog)

Hi !

I have broken Sansui G8700DB, and now looking for 2sb681 + 2sd551 transistors (originally Toshiba, but any other respectable company like On Semi is also OK).
I seen them on sale on eBay, and they look like counterfeit. I cannot state it is as fact, but somethings look really suspicious. For example, on original transistors "Toshiba" logo printed in curved italic, on those for sale on eBay - just in plain text. I'm in doubt Toshiba have decided to change logo style, but who really knows ??
Any good and reasonably priced source in Europe is OK. If anyone can suggest analogs in TO3 case, I would be very grateful. 2sb681 / 2sd551 seem to be discontinued, but I do not know substitution part #.

Thanks in advance for any suggestion(s).

Hi
Don't buy from Hong Kong or China - they are fake. I did order, opened up the cans and found the chip was only 1/4 of the size of teh real ones....so probably just rebatched 2n3055 all of them.

Check out this one:
Who needs Toshiba 2SD424/2SB554?
If you can use them in your amp ( check the specs) they are still up for grabs.
