From a Beocenter 2100, type 2442 , TR7 in the ps for the protection circuit/
output relay driver circuit, but I don't have the manual for this one.
It is between TO92 and E-line, slightly smaller than TO92 with a small flat
on the curved surface
It in pnp , marked
115
4XF
so not BC115 or 1154
or 2SB115 or 1154
Would it be short for B&0 number sequence preceding with 8320 so 8320115 ?
and 4XF as date/batch code for 1984 perhaps
