A very packed BC21.1

I dare this BC21.1 has the highest density of parts in there. I didn't think I would able to fit that much in there but after years of being bugged by many owners I thought I would try it. So I did.

From now on, if anyone has a BC21.1 want a BAL input, and output, it is possible. As long as you are willing to live with a separate power supply.
