Digi-Key - 2SA1943-OQ-ND (Manufacturer - 2SA1943-O(Q))
2sc5200
Wont either of these places ship to you? I believe they are based in the USA but will ship airmail directly to you for what is £12 here in the UK and shipping is free if you spend over a certain amount with them (£50 in the UK).
I've currently got an order from Mouser that is in the process of being shipped. They provide you with excellent tracking services via UPS, notifying you each step of the way how your parcel is being processed. My parcel has been in transit for a little over 24 hours and there's 13 individual entries on it's progress during that time.
They also give you the option of either paying VAT when the parcel arrives, or they can pay it for you (I assume this means you just pay them more), at the time of purchase.
I would be very surprised if the products both stocked weren't genuine.
Either way I ordered a few 5200/1943s myself so I can let you know if they appear genuine when they arrive.

Yeah, I wouldn't consider ordering c5200/a1943 from anyone BUT a major electronics distributor. Digi-Key stock is authentic. In fact I asked about this by email once and their Toshiba product manager called me back almost immediately and assured me they *only* buy them directly from Toshiba.
Digi-Key also sells Fairchild versions which also have a good reputation. Fairchilds also come in smaller TO-220 packages, and larger TO-264 packages to suit different power dissipation requirements. These are called FJL4315/4215 if I remember correctly.

I have bought from this company- LittleDiode Ltd.
I am happy with the product being genuine etc. so should be OK for what you are looking for.

Jebus Christ the prices... 4x what Mouser charge for a 1943.
There seems to be a lot of inconsistency between prices online, so obviously it pays to shop around. I bought from Littlediode 4x BUV20 trannies for my NCC200 build at about st£7 each (prices have risen since then to about st£9 each), which is about the same as Mouser. That compares to Farnell at about st£17 to st£18 each. Mouser do not include any taxes (VAT) which for me in Ireland amounts to another 22% paid on delivery.
This French site also has what you are looking for and you can buy just one item (no need to purchase in 10’s), not the cheapest but not the most expensive either - Awatronic, composants lectroniques I have no personal experience of them though.
Hope that helps

the order arrived today.I've just ordered 25pr 1943/5200 and 500 other transistors from ProFusion (UK).
I'll report when I have had a good look at them.
The 1943/5200 look genuine.
The markings are similar to what Tosh show on the datasheet.
There are no codes stamped in the little glossy indents.
The lot nos are 927 with an underscore below the 27.
This is preceded by a tiny o near to top of the 9 (like a degree symbol in degreesC) and 849 again with the preceding degree mark and the last two digits underscored.
All the others are stated as unisonic manufacture.
I found this test schematic on a Spanish website. supposedly it will spot the fake 2SC5200/1943 devices. I don't know how accurate that really is. I suppose it depends on what device they choose to use as the base of the fake. but i built the circuit and tested a batch of devices i purchased a while back. all passed, all are still working happily in the amp they were put in so????

What reading differentiates a genuine from a fake?
can someone translate that for us?
Something along the lines of......
"The light must remain completely off, and turn on only when the switch is operated. Counterfeit transistors are commonly short-circuit, making the light turn on regardless of the position of the switch."
Counterfeit transistors are commonly short-circuit
Are they? I thought commonly smaller dies are used (cheap small power bjt in high power bjt case) and not short circuit.
A shorted bjt will not stay unnoticed in an amp.
Have fun, Hannes
