Every tech knows the frustration of not being able to get the correct parts, I thought I was going to be in that situation with a Yamaha M2.
I had the opportunity many times over the years to get Yamaha M2, high freq Toshiba TO3 output transistors and to stock up on them, but time passes and you put it all on the back burner, the alas comes the day and you need them.
China has got a lot to answer when it comes copies; they print part numbers like its going out of style, so be wary on ebay, it might not be fabricated with the same technique.
I tried just about everywhere for the Toshiba 2SA1051A and 2SC2461A, knowing this was going to be a challenge.
Dalbani had NPN only and they looked pretty motley so I gave that a miss..
I remembered I’d purchased from HB Electronics in CA, so I checked their stock, and low and behold they still had them on their stock list.
I ordered 3 of each but they had no brand listed and no “A” version.
It was important to me to get Toshiba “A” version printed on the device.
I waited eagerly for the package, thinking they were at best going to be at best, unsuitable Sumitomo , as I not sure whether Toshiba licensed that technology to 3rd parties.
This is what arrived for $40
