Electronics is located in Anula, a suburb of Darwin in the Northern Territory, which is in the middle of the top of Australia, and is a privately owned and operated Australian family business, totally dedicated to Audio.
David Edwards built his first amplifiers in 1963 (all valve of course) at the age of twelve, in Strathalbyn, near Adelaide in South Australia, and hasn’t stopped building and repairing since, having decades of experience working on Radio (A.M., F.M., H.F.), Television, and Audio amplifiers up to and including 300KW in Class ‘AB’ and ‘D’.
About my credentials,,, I have ended up working on 500KW [that’s half a million watts] audio amplifiers as used in the Radio Transmitters at Radio Australia. They can send a signal around the world 3 times. I guess what I’m trying to say is nothing scares me tube wise.
After eight years of digital microwave radio repair work, the call back to audio rang loud. The main aims of are to help audio builders and musicians, as much as possible, in their quest to get ‘the sound’.

OUR DUTY OF CARE NOTES:
If you are doing anything related to electronics it is very likely that you will be working on, or near equipment which has the potential to cause serious or fatal injury to yourself, a family member or friend. The following points are a guide only, and are given in good faith, only because we have had experience working on equipment designed to use up to 30 thousand volts.
- Never work on live equipment;before removing a chassis, switch off the power and remove the power cord.
- Wait 10 minutes or so before removing the chassis. The 10 minutes should allow storage capacitors to discharge, BUT there is NO guarantee. If you are not familiar with capacitor discharge techniques you will need to seek professional advice.
- Remember that electrolytic capacitors connected with reverse polarity or the incorrect voltage can explode. Film capacitors can also explode. Semiconductors in high power applications can explode in unusual circumstances e.g. radio frequency instability or mains surges from lightning.
