Pre-made power supply for Quickie

[boulos]

Bumping this thread up.  Since I use the Quickie occasionally, solving this issue is important for me and preferable over taking out a 9V battery every time I'm done listening.  Can anyone else with a stock Quickie 1.1 + PJCCS measure -reg when the Quickie is off.  I'm getting ~0.25V which means the batteries are constantly draining?

Thanks

   Measure from where to where. I use mine daily and get close to 100hrs. on battery's

Hi,
If you use it daily, then the leakage when it's off will be irrelevant for you.  It becomes relevant when you keep it off for a while (weeks at a time), then turn it on and find that the batteries have been drained enough that they're no longer usable.

Measure -reg (on the PJCCS board) to ground (with an instrument that can measure small voltages).  I get 0.25V.  From earlier in the thread, here's the path and list of measurements I took (all to ground):

IB -> D1 -> R @D2 -> R2 -> R3 -> R between T9 and Ground

The voltages along this path are:
35.14 -> 34.71 -> 34.45 -> 5.54 -> 0.26 -> 0

This means that current is flowing along this path and the batteries drain slowly over time.

This is resolved now.  It turns out there was an error in the PJCCS manual for the Quickie 1.1. Thanks to PB for the excellent support, for identifying the issue and sending me the fix.  After updating the board based on the new instructions, there is no more parasitic current leak.  As a test, I left the batteries in the Quickie for almost two months while it's off, and they measured the same as when I put them in. Attached are pics of the updated PJCCS board.

Interesting, i'll have to reverse engineer the circuit to see what has changed as its a different layout from mine.
