Re: Wells Gardner transistor sub

Thanks Roger,
I figured it was probably a general use, low current transistor. I just
thought there was a more "Arcade monitor" choice because it's the only one
on the board with that number.
I have a bag full of MPSA06 transistors and matching comp, MPSA56.
If anybody needs any let me know.

Jim
