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.<\/p>\n

You will see what I’m saying when you see a few of the following additions:<\/p>\n

The previous modules are very handy for point to point wiring as well as connecting transformers with different configurations, etc.<\/p>\n

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:<\/p>\n

For signal input\/output I use the high-quality Jakeband RCA connectors. The plate has also a GND connection if needed:<\/p>\n

\"\"<\/a> Same PCB plate can be used with a generic RCA connector:
\n\"\"<\/a>Speaker connector:<\/p>\n

\"\"<\/a><\/p>\n

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:<\/p>\n

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:<\/p>\n
