As time is very limited these days, I’m focused in continuing my modular building approach in LEGO style. I have developed several PCB modules which are flexible to be used in multiple amplifier and pre-amplifier designs. Now, I used the power of PCBs to build some additional supporting modules to speed up my breadboarding over the IKEA boards. Not the most elegant approach, but building becomes a very fast process this way.
You will see what I’m saying when you see a few of the following additions:
The previous modules are very handy for point to point wiring as well as connecting transformers with different configurations, etc.
Now for HT and LT connection between boards (e.g. power supply and amplifier) I use extensively the Neutrik NL2 series. They come with 2 screws in diagonal array. Here is a small plate adapter:
For signal input/output I use the high-quality Jakeband RCA connectors. The plate has also a GND connection if needed:
Same PCB plate can be used with a generic RCA connector:
Speaker connector:
For sockets, here are a few examples of Octal and Loctal dual socket modules as well as 7-pin miniature socket and UX-4 from Jakeband:
Here is a handy INS-1 Neon module for HT indication. It comes with a built-in resistor and connection and holds tightly the INS-1 Nixie bulb between the 2 plates:
There are a few more to come, this is just a snippet.
Ultra nice. Will these be for sale in some form, or will we have access to gerber files?
What PCB software do you use?
Please advise.
Thank you. I may sell some, need to find the time. Not sure if is worth doing it. When you do the PCBs in small batches and you factor in the development costs, shipping, import duties, etc. It all adds up and make it a bit expensive for some. So not sure if I’d do it.
