The circuits aren't anything special, or for that matter old. The transistors are 2n2222 and 2n2907. Some of the pins are bent a little, but are easily straightened. High quality.
You're bidding on ONE. First come first serve. When you order, describe you're preferences.
I have a numerous ICs and other items listed HERE.
If you want to make an offer on multiple listings, I recommend contacting me. Ebay's system isn't designed for that (I'd make a special listing).
If you order from more than one listing, contact me for an invoice BEFORE you pay. If I end up making a partial refund, I won't include ebay's 15%, which they don't refund to me on a partial refund.
Like every other seller, I would appreciate it if you contacted me, rather than leave negative feedback, or less than 5 stars.
