[229] Free AC128 Transistors!

Date: October 8th, 2008 | Comments : [4] | Categories: DIY.

AC128 transistorI have a large pile of AC128 transistors that I sorted from recent bags that were purchased. These devices did not meet the specs for leakage or gain that I set for the transistors that I sell. You can have 2 of these leaky transistors for only the cost of the shipping materials and the postage. I calculated that $2.50 should cover the padded envelope, mailing label, plastic bag, print toner, Paypal fee, etc. (Postage and the envelope are $2.14 alone) (Limit 1 per person!)

If you want 2 of the leaky AC128 transistors, just hit the Paypal button below. Some of them may be suitable for fuzz or booster use, but no guarantee! Can be used for germanium buffers. Offer limited to US addresses only!

I would guess that 20% to 35% of these transistors will fall within the 350uA to 500uA leakage range. This is adequate for a buffer (definitely) and a booster (probably) and even a fuzzface (maybe). The leakage of the rest of them will be higher than 500uA, though still suitabe for the Ge buffer I have previously posted.

[…] the leaky germanium transistor buffer. This is an especially good option since I’m offering free AC128 transistors that can be used for this purpose. The Ge buffer can also be built on stripboard or on the […]

Nice website. My english is not so good. Have you a tip for me to translate? Hope for an answer. Thank you!
