Some builders for the F5-HA bought from Alweit before.
Tested genuine, good service.

Disclaimer -- I have not bought from him myself.
So just quoting others I know.

Vendor write:

Genuine Toshiba 2SK170BL/2SJ74BL high transconductance JFET complimentary pair | eBay


" If you are ok with going by the printed parameters, that is what will normally be included with each sale.


In which case, all you have to do is ask if we have what you want.
If what you need has to come from "curve tracing", well, you will need to be very specific and be willing to work with us."

This Guy want to do good curve traced matching.
Yes he need experts help for excellent quality matched pairs.

If you have a good feeling about this particular vendor, get two matched pairs, test them, and let us know what you find. This is constructive for the diyAudio community.

First fact few jfet's 2SJ74 | 2SK170 pairs was sold.

Wait a little for the buyer(s) feedback.

Other semiconductors from this new shop have received 100 % smile 5 stars.

If this vendor writes, he is open minded to personalize or do better test DUT method curve traced
for potential buyers in the USA or worldwide. Honesty and positive attitude.

Yes, I will probably try to buy from him in the near future of deep Toshiba jfet's crisis
Who knows in stock better equivalents ?
