Its all about the Music
Very busy at my real job so less time for this work, but a quick post for this Constant Current Source mod for the differential pair on the 999 power-amp.
I was trying to find a drop in solution, and didn't have much luck, but as luck would have it, I have hundreds of these LM334 which is used as a temperature sensor in the Crown Macro-Tech amplifiers. These devices can also be used as a Constant Current Source.
So I got to and came up with an adjustable solution on a perf board, put some legs on it, and slipped it onto the driver board, done.
I have only got as far as setting Bias and DC offset, I haven't heard it yet, but I hope to have a listen tomorrow night.
Heres a few pictures of the development. I'll explain a bit more about it when I have some time...
