Having enjoyed most success with those glowing glass bottles, transistors are a bit of a mystery.
Would there be very wide variations in these old transistor types?
I just wonder how many examples of OC81 you'd have to go through to get particularly good examples.
I think the circuit before me may be a bit of a bodge. I would be quite happy to name it in a Private Message to comply with the Forum rules and gain useful advice.
