Need Tannoy Limpet Amp Schematic

[musika]

Does anyone know of a schematic for the Tannoy Limpet amplifiers?  I am working on two of these.  One had a dead power transistor and the other needed a new recapped power supply.  I've recapped both and now need to adjust the bias and was hoping to find information on that.  There is a 250 ohm single turn trim pot. Can someone help me with this procedure?

There is a couple of numbers on the amplifier card on this image, but searching has not produced anything.
