Default GB 8 piece matched Toshiba 2sk170 BL grade Jfet's

Hello,

I am starting a group buy for 8 matched Toshiba 2sk170 BL grade Jfets

total 15 slots ( 2 pre-ordered- hifibluedevil and lancer -so actual is 13)

I will purchase an unopened bag of 200 transistors from the following reputable Ebay seller:

2SK170 Toshiba J-FET Transistors Qty 200 - 2SK170BL - NEW - Audio Low Noise | eBay

I have purchased from this seller and NP verified the seller.
I will match the transistors with the following method:
Transistor matching
The Jfets will be Idss matched to within minimum of 0.2ma (hopefully much closer.) The goal is to provide as many matched octets as possible if not possible I'll deliver at least closely matched pairs of quads.

The seller told me in his experience 70% of the transistors will fall into the7-9 ma range so that is most likely what each participant will receive. If matching is not possible for all participants I will refund from the bottom of this list until all matches delivered. Conversely if more matches are available I will open more slots.

Price is $40 per each 8 pieces set. Plus $8 for priority USPS shipping in the US. Shipping outside the US will be actual. Payment through PayPal.

Group buy will remain open until at least 12 paid participants at which time I'll purchase the transistors and begin matching and shipping.

This is my first group buy. I'm hosting it because I am building the B1 Korg Nutube Preamp. I am actually going to build 2 side by side, as a fun project, 1 from the diyaudio store that came with fairchild 113 jfets and one from this GB:
GB B1 Nutube PCB with integrated PS
So 1 set of the jfets are/is for me.

Responses to the thread or PM's will receive a PM with my paypal info. I'll keep a running tally of who's in and paid.

nice one dabore84! will you please PM me your address so I can calculate the shipping?

Also for those outside the US please send me a shipping method suggestion as I am no expert on shipping overseas.
