Default A few obsolete Power Transistors for sale (EG OC28)

Iíve had these for decades and will never use them so they might as well go.

Some may be NOS, but I think most are used. Iíve tested them all and have shown the results below as compared with Towers International Transistor Selector Book. Iíve put them into three packs of five. Iíve tested most of them on my Peak Atlas DCA55 transistor tester, but that canít test the higher power ones Ė OC28s etc, so Iíve tested those on two Chinese testers which will cope with them. Iíve shown the test results obtained for each, compared with the Tower's data.

Looking at prices on e-bay, from Langrex, Cricklewood etc, hopefully, £10 per pack inc post might find them a home.

No hat.

PayPal or a cheque is fine - please PM me your postal name and address if interested.

OC28 Towers HFE: 20 min. Actual HFE: 136

It seems that there's zero interest in these, so the thread can be closed please Mods.
