Beginners Guide: DIY Hifi Amplifier Upgrade, Power Supply
Following on from our speaker crossover upgrade video, Elliot decided to buy a Cambridge Audio amplifier from eBay to see what DIY upgrades (Nick) we could do. What this amp provides at the secondhand price point of £40-70 is plenty sufficient: four line inputs, treble and bass controls, tape monitor, space for an optional magnetic phono preamp and a sound when combined with the newly upgraded speakers that was, to some surprise, pretty good. Not lacking in definition, already this little setup started showing promising signs. In this video Nick takes us through opening an amp for the first time and upgrading the capacitors in the power supply. Check out some of our other tutorials on the HiFi Collective site at https://www.hificollective.co.uk/videos To see the capacitors use in this video please head to https://www.hificollective.co.uk/comp...
