Tested the other channel on the preamp board... oh yeah... it works! Smile

Now, time to do some burn-in testing.

BATTERY TESTING Part Deux...
Hooked up the 2-ch pre to a Tekkeon battery... run some music signal and listened to it on my monitors... everything connected using test clips. What's the current consumption of the preamp? (i.e. with the VU Meters turned off)

* You can see which LED is lit up on the Tekkeon battery which designates the output voltage selected.

TESTING AT 12VDC ... of course no surprise here, it will work


MAX voltage input is 14VDC...


Okay, no surprises there...

Just for kicks... I decided to lower the input voltage to see how it holds up... At what point will the sound disappear and the pre stops working?

Let's try 9Volts... still works.



How about 6Volts... surely it will drop at 6Volts... but nope, it's still working.


This is disappointing... ;D Let's try 4.5Volts input... That should kill it!

Nope... still working...

Okay, the lowest setting on the Tekkeon battery is 3 Volts... let's kill this pre, die die die.


Unfortunately, it's still working. Sound is still coming out of the pre. I've been listening for the past half-hour with the pre running on 3Volts from the battery and no problemo. It's still going.

Nothing feels hot. Not the battery, not the preamp, not the various chips, not the PSU section. Everything is C.o.o.l!

Sooooo, you can say I'm pretty pleased about the results.

PS: Notice my new multimeter? Yep... It's a Fluke, baby ;D
