Thanks Salas, I will experiment with different parts...even though im very pleased with parts already used...but will be interesting and amazing if things improve further!!!

Keep the current mix written down as a reference since it seems OK in your application so you can have a fallback mode. How is drift as you are without a trimmer?

Yes good idea!! Voltage drift after 1 hour was non existant!! was a solid 5.4v throughout

There will be some minus drift in some applications with larger voltages and currents for mainly resistive means of Vref if preferred. I got -0.1V in 30mins in my 15V prototype with 2 leds and a Bourns trimmer. Which I trimmed up for when hot.

Congrats Alon, looks like you figured out the MiniKit's ok ?

Yes thanks Teabag, everything was very straight forward. Congratulations on a well organised and successful group buy

Wich one 10mF 80V? 35mm diameter to fit in the boards it's a little bit difficult but did you do? all questions is because I need to buy capacitors for the regs.

necplusultra · 16th July 2011, 10:31 AM

would it be possible to tweak in any way the negative to use as a positive (ie: reverse board and/or parts)

The BHC was not on the PCB but on a perf test. 63V it was.

T-Network 4 pin mounting? what about the sound?
