18 Watt Cage Amp
is also available as a kit for experienced builders.
A layout and circuit diagram is provided, with main components
loosely mounted on the chassis for safe carriage. Kit includes
everything you need to build a fully working 18 watt cage amplifier.
This kit is not really suitable for first time builders without experience of electronics or amp building. All valve amps involve high voltages and unless you are confident and aware of the dangers, choose another project to gain experience and practice.
We offer an alternative (easier to build) conventional chassis type amp with the same components and the same sound, complete with a superb hand made head box.
Please contact for details.
