First time on this site. I just registered. If I make some mistakes, please forgive me.
I have a board set up with 16 - 2N3055's. I hoped to use them as switches to power some coils. I have designed a TTL logic circuit that works well and gives me the logical highs and lows to turn on and off the transistors. My problem, I know very little about transistors. I'm not sure what I need to interface them from the TTLs. The 3055's will be switching 12VDC coils at about 2.5 amps.
