TO1 packageCan someone tell me a suitable replacement for this
low-power pnp transistor type ?
And - even better! - where they may be obtained ?
They were used in the Marconi TF2700, but I can't
even find a spec for them now.

Thanks Graham, and for the list of early transistors."Jim Hawkins" <jimhawkins@manx.net> wrote in message

is a useful list of early transistors.
AC128 seems to match the main parameters.

Gosh, you got no brain, first check your spec for this part, second go through transistor selection guide. Check with Motorola databook dummy.Can someone tell me a suitable replacement for this

#1 your listing is incomplete, Ib is very important! #2 how can we trust your recommendation? Care to provide the link the the datasheet?"Jim Hawkins" <jimhawkins@manx.net> wrote in message
