We do own several of these cards but don't use them anymore. The 1010

signals and provided digital multichannel connections. We still have
them around lying in plastic bins (some were recycled). Such a shame.
For old timers in this list the power supply issue on the 1010 is well
known. The voltage doubler (or quadrupler?, I forget) capacitors in
the power supply blow up after a while due to bad design. The 5V rail
is still there but the analog voltages go down or disappear, so the
card still "works" but all audio is gone or badly distorted. Replacing
the capacitors fixes everything (visual inspection can easily reveal
if that is the problem).
Hi Fernando,
IIUC there are different 1010 models out there and some are using
external power supplies and those power supplies seem to be be very
cheap.
I commented on the plain 1010, that has an external "brick" power
supply, a pci card and a rack mounted D/A A/D unit - that is where the
bad capacitors usual are.
I have never used a 1010lt so I know nothing about it... sorry...

Regarding this

and some reading this card, the "LT" model, has got no external power
