Manhattan All Manhattan pad kit utilizing 3/16" square pads.  No Islands to cut, no drill press needed, all pads - easy construction
Islander ... Similar to the original Islander audio amp circuit kitted by the NJQRP Club, but with significant tweaks and improvements.
Audio Amp ... Yep, that's what it is.
Specifications and Design Features ... Very quiet noise floor, 65 DB power gain, small 2"x3" board, all Manhattan constuction, and Altoids® Compatible!.
It can be driven to about 150mw output with clean audio and room filling volume.  That much power into an 8 ohm speaker is LOUD.
The passband response curve shows a broad peak at approximately 500 - 1000 Hertz.   The input impedance is 100K for superior isolation and light loading of preceeding audio stages.
So this is a small, powerful, quiet, easy to build speaker amp which will match up nicely with your earphone CW rig.
Uses ... K8IQY originally developed this little amp for speaker use with the SW+
series from Small Wonder labs.   It would be especially useful with the small transceivers that are popular today.   The SW++ series from Small Wonder Lab, DCxx series from
Hendricks QRP Kits, Rockmites, the AT Sprints etc.   In addition it's useful for your bench amp, any headphone output receiver, and with suitable coupling it would make a nice headphone amp also.
The Kit Includes ... All components, documentation, and associated parts to build the amplifier complete, less connectors and enclosure.
