The printed circuit board is now being populated. As you can see I am having to pillage previous versions for parts to keep the cost down; there are some very expensive parts to be bought yet. It feels so good … Continue reading
The layout of the PCB is progressing well. I spent a few days getting the hardware (as in the old physical sense, not the new computer speak) right which gave me the size of the PCB. I now have a … Continue reading
At the moment I am working on a friend’s Quad 405-2. It has never been serviced and is well over 30 years old. Electrolytic capacitors have a limited lifetime, mostly 2000 hours, special ones more (the ones I am using … Continue reading
I really do not like using metal switches for HiFi. Electric currents (including small signals) produce magnetic fields in surrounding metalwork. Even aluminium produces some bizzare effects when a magnetic field is introduced to it – look into this on … Continue reading
I have now started work on building the amplifier board. This contains the pre-amps as well as the power amps. I’ll add a photo once the board is completed.
In preparation for building the Lab Power Supply Unit I need to know what components to order. So I am currently creating a Stock Control System. That has meant updating all my circuit diagrams and component listings. Just in case … Continue reading
