The preamp build is progressing, albeit slowly. I tried a new breadboard construction approach. A nice Ikea chopping board was used to build the front and back wooden panels. A pair of aluminium squared section rails are used to provide support and hold a pair of top plates for the power and audio connectors. As a bonus given the low power consumption of the filaments, I will use these rails as the heat sink for the Rod Coleman filament regulators as well 🙂
All in a very compact design as I literally ran out of space for further equipment in my living room!
Nice “chassis” Ale, I like it.
I always regret that I do not have Ikea nearby.
Thanks! I don’t know exactly what type of hardwood is. Some Asian hardwood in strips which I think they are glued and compressed. I’ve got the idea of using the IKEA chopping board from someone else in the forum. A cheap alternative, however a pain to cut properly as the chopping board comes with angle cuts!.
It does the job pretty well, need to oil it still.
The good thing of this approach is that you can add modular top plates and have easy access from the side to solder and good ventilation as well as a plus
Cheers
Ale
Thanks for info.
I know advantages of wooden chassis for tube gear. Metal box I used once and never again:-)
Best wishes Ale.
Yes. Milling is a pain. I hate metalwork. Mechanical work is really painful. And we cannot avoid that in the amp build process unfortunately!
