I will wait for the amount to reach $100 before actually donating it to the forum, this will reduce the amount that goes to paypal.

Luke,

Thank you for the complement!
I have heard from some moderators that this forum is still running in red, which is not good.
I wish that I can raise some funds for the forum, to help making it sustainable for the benefit of everyone, myself especially.
Paypal easily takes 4-5% of the order amount, I think the forum should deserve a certain percentage too, for the convenience that it provides to both buyer and seller.

Dear AuroraB,

You are not the first on to ask for unmatched J74.
The problem is, I buy J74 from sources that are accessible to you all too, and at the same price as you could get.
No there is really no point for me to sell unmatched, as I need to charge price higher than other places to cover my shipping/packaging/paypal etc.
If some one knows a reliable source that can get thousands of J74 for a good price, please let me know as I will be the first one to buy it.

Good to see people helping the forum out, I didnt know it was making a loss. I would have hoped that it would break even at least with advertising.
Sell it for one billion billion dollars to Murdoch:D

Payment received from:
DUC985 R100*4
ICHIBAN K170BL*50, K170V*50, R100*4
RetroAudio 2SK369BL*100
These orders will be shipped out on Monday 12th.

I'm sorry for the delay for all orders containing SemiSouth JFET R550.
I should be able to finish matching and ship them out on with the week starting on 19th of April.

From Monday 12 April to Friday 16th April, I will be oversea. So reply will be slow at best, and no shipment is possible. For all orders and payments received before Sun 11 Apr 12noon GMT, I will ship them out on Monday 12th.

measured 2SK170BL

For my batch of 100, subject to the measuring limitations in house, all were within the BL range of 6.0 to 12 mA.

Results ranged from 6.3 to 10.8 mA. Matches available with grouping predominantly below 8.1 mA (81 0f 100), with scattered singles and duals above that (19 of 100).

Happy to have gotten these. Projects can continue.

Thanks to Zhou Fang

Zhou & all

My measurements were done with the devices still in the paper tape. I recorded the results on the tape next to the device.

I set up a jig with spring clips that allowed changing the DUT. One clip provided the contact for the Drain. The other clip provided the contact and bridge between the Gate & Source.

In my batch, I see few matches for devices next to one another. My suspicions are that the devices are placed on the tape in a random fashion.
At the end of measurements, I returned to the first device measured and got the same result. I did this out of concern for drift & change in applied voltage.

I wish the best to you
