Hi Franky
I am after some banana plug socket combined Binding posts Red, White, Blue, Black and Green. Maybe 12 of each. Can you get something suitable. Attached is a photo of similar ones.
Also 1 metre retractable ? shrouded banana plugs leads Red, White and Blue.
Some big and small (if you have them) crocodile clips the bananas can plug into. Red and Black. 4 of each so 16 in all. If you have something suitable.
They are going to be used at up to 400V rms and in student labs. so good quality.
Let me know what you can do
