Phil Wait

After a long career in the Australian medical alarm industry (VitalCall medical alarms), Phil returned to an earlier passion for designing audio amplifiers.

Forty years earlier, while staff engineer at Electronics Today International magazine (ETI), Phil developed and described many do-it-yourself electronic projects for home constructors, including a 140 Watt amplifier for guitarists that used four EL34 output tubes with 750 volts on the plates! Those were the days!

So, rather than retirement, getting involved in DIY projects again seemed like an obvious thing to do, and fun too. So, why not another valve amplifier? Shortly after the RedRoo SE5 amplifier was born, and over the past couple of years the design has been refined to make it as easy as possible for DIY constructors. Later, the PR5 vinyl preamplifier and a novel highly versatile guitar amplifier, the "Flying Turtle" were added.

The SE5 has proven extremely successful and reliable, with many great-sounding amps built by people from all sorts of backgrounds. The new preamplifier and guitar amplifier are also gaining popularity.

Phil is also the past Chair of the Australian industry association for Medical Alarms, past President of the Wireless Institute of Australia (WIA), and has represented the interests of medical alarm providers and radiocommunications users on various Australian Standards committees. For downtime, Phil races yachts (yes - the "Flying Turtle") and rides vintage motorbikes, if you can call any of that relaxation!
