Perreaux "house named" components...

[Mike Deblis]

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

I'd hazard a guess that the first is a generic small-signal PNP
transistor and the second is a generic small-signal NPN transistor. Are
the output transistors labeled "pslp" and "psln" too?

And what do the actual transistors say on them?

Tim.

I've always though the Perreaux's were a MOSFET amp. Well I know all the
current ones are, pre and power. I've I thought they always were - they
advertise that fact all the time, saying they've been making mosfet amps for
over 25 years so they are experts etc etc.
