These last few weeks I have been building a "Chiara" head amp to compare and possibly replace my original John Linsley Hood discrete design. Given Johns recent sad passing away I wanted to make this project something of a tribute to the man who has given me and many others so much pleasure with his superlative designs.
I would like to share my efforts with you. The case is scratch built from two metal boxes from Maplin.co.uk mounted on a piece of MDF. The front panel is 6mm smoked plexi and the case sleeve is also made from MDF.
Using the two boxes, which are physically separated, allows the original grounding design to be used whilst allowing a "single box" finished case. It also helps to keep supply induced hum and noise to a minimum. The extra PCB in the amp section is an input switching circuit. The only thing left to do is add the remote control circuitry which is still under development.
With lighting in place.
The finished unit switched off.
Switched on. The light around the volume control looks bright in this pic but it is really quite subdued. My digicam is not too good at shooting lit leds or black mirror shiny surfaces either.
This is no ordinary power light. The writing only appears when the amp is powered on. J L Hood - the man who inspired this project.
I am thinking of giving my JLH mono blocks the same treatment.
