Description

Looking down on the board:

• The Pre-Amp is in the bottom left corner.
• The Volume is in the centre.
• The Power Amp is on the right hand end with the two Op-Amps bolted to the heat sink.
• The charging circuit is in the top left corner.

Notes

• The battery used was a 9.6v Ni-Cad racing pack.
• The box was labelled using transfers, which are surprisingly durable.
• The blue wires are the speaker wires.
• The NK connector was a push fit, and then sealed with Epoxy. It is important to fix the connector firmly as it does not have any mechanical support (such as a lock nut) and will suffer a lot of abuse.
