Phil Wait
Forty five years ago, 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, and after a long successful career manufacturing medical alarms and providing medical alarm monitoring services, electronic projects for home constructors seemed like a fun thing to get into again. So, why not another valve amplifier?
Shortly after the Red Roo Kits SE5 tube amplifier was born and released, either as a full kit of parts or as a solderless version to make it as easy as possible for DIY constructors. The PR5 vinyl phono preamplifier was added in 2022 and the 'Rockstar' guitar amplifier in 2023.
The SE5 tube stereo amp and the PR5 tube phono preamp have proven extremely successful and super reliable, with many great-sounding amps built in just a few hours by people with wide-ranging experience.
More recently, RedRoo has changed its name to SPOTFIRE, and Phil is currently working on a new 35 Watt hybrid amplifier design (to be released shortly).
Phil likes listening to his collection of tube amps, owns several vintage motorbikes (1976 Honda 400F and a 1979 Ducati SD900) and fast cars, has been an amateur radio operator forever, and yacht races regularly on Sydney Harbour.
Phil gets his biggest kicks hearing from people who have built one of his amplifiers.
