i wont buy Semiconductors for F5T
2SK170BL(GR) or 2SK366BL(GR) Q1 1 Idss = 6 - 7mA 2pcs
2SJ74BL(GR) or 2SJ107BL(GR) Q2 1 Idss = 6 - 7mA -2pcs
2SC4793 4pcs
2SA1837 4pcs
MUR3020WT-16pcs
FQA12P20 4 Vgs matched to 100mV or less -8pcs
FQA19N20 4 Vgs matched to 100mV or less -8pcs

How i may pay, (paypal - is ok),,, and im in russia you may send to russia?

Exactly 5 years ago, we bought some FQA12P20 / FQA19N20C in a GB for our F5 test build :
http://www.diyaudio.com/forums/group-buys/122074-eu-mini-group-buy-fqa19n20c-fqa12p20.html

They were from Digikey and are still in original Fairchild tubes.

Since then it is well known that we have changed over to the F5X and Toshiba power devices.
We still have 30+ pairs (single point Vgs prematched) left with no use in sight.
So we are happy to let them go to single ended F5 builders who do not like Toshiba's, for whatever reason.

They will be offered as NN / PP matched quads, xen-audio curve tracer matched for both Vgs (<<10mV, normally <5mV)
and Yfs (<<10%, normally < 5%), at 24V 0.3~2.5A, at 65°C case temperature.
This represents the exact working conditions of the FETs in a standard F5.

Each subscribers limited to one set (4 FETs NN-PP) per person, unless under-subscribed.
Price depends on curve tracer matching yield, but tentatively 250~300 HKD a set, all inclusive.
(Paypal charges, registered post world wide, etc.)
We do not cover postage losses, as usual.
Delivery some time July 2013, since matching schedule is totally full till then.

Any interest ?
