I am currently researching and designing electrical audio equipment, example devices:
- Tube and solid state guitar amplifiers
- Guitar effects pedals
- Mixing / filtering units
Some of these devices will be mains powered and some low voltage.
For context I am in the UK and hold a Masters' degree in Electrical and Electronic Engineering.
I have had friends, relatives etc approach me to ask if they can buy some of my products.
At present I do not plan to make a business out of this but it could be a possible future consideration.
The price I would be selling the equipment at would not warrant £1000's of test certification, as I do not have the money for this I would prefer not to sell if test houses are the only option.
My primary concerns are safety and liability.
What safety standards do I need to comply with and can I self certify?
Can I remove / reduce liability by selling as a kit product / prototype?
I notice people online selling amplifier kits, presumably they are not liable for incorrect wiring / use.
