Can 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.

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

Thanks Graham, and for the list of early transistors.
