Hi,
I'm tying to identify some PNP/NPN transistors in an old (c. 1985) Perreaux amplifier. The manual and schematic only refers to them as "pslp" and "psln" - other active components all have their proper p/nos. The amp is a rather lovely PMF 2150B - a classic of its time and worth restoring.
perreaux are not being helpful on this.
Many thanks
Mike
