Wrong/bad aquisition?
phobik, totally understand what you are saying and yes the scope card is very powerful but not something I would recommend for quick and easy setup "toying around". If you can find a cheap little behringer mixer then you will certainly be able to use it for what you want but you will need to get familiar with how scope works.

A good recommendation....

yes, you can indeed save a lot of cash with some DIY if you consider the 'raw' material costs - but time and making of printed circuit boards can't be neglected...
In that sense you might start with tube technology using point to point wiring - avoid high voltage layouts for the beginning, tho
Before thinking DIY multichannel converters take a comfortable seat - you cannot even beat Behringer and there's at least one product (with less features) for about half that price (dunno it's quality) afaik.
An Adat with worn out drive is the only thing below $100 - it looks cute with all it's meters, but it's a bit bulky
cheers, Tom
ps regarding pre-amps:
my 'main' bass is serviced to get new pickups, so I used another one I once had aquired because it seemed to be well crafted, but then didn't play it much because I just didn't get along with it's tone.
I can only say I really didn't expect the Radial pre-amp to make SUCH a difference
I definetely wouldn't have bought the 2nd bass (which is now modded for almost twice the amount I paid for it...) if I had played the first one through that preamp.
Fortunately both instruments feel and sound completely different, so I don't end with duplicate stuff

No - we're talking on the pre-amp side here and there are tons of designs running with 12 to 48V.
Of course (almost) all classical amps from the 'tube era' had (life threatening) 200 to 400V supplies - for simplicity, as it was needed for the power stages anyway.
What do you think is in all those small tube equipped preamp DI and stomp boxes or tube mics ?
Since many tubes contain 2 active elements (f.e. double triode), there are pretty compact designs possible and most of all: no expensive (if available at all...) output transformer is needed in the pre-stages.
Tubes have no 'obscure' behaviour like op-amps which can easily drift into high frequency oscillation due to physical arrangement of parts, something hard to detect without proper gear.
So it's indeed a perfect starting point, additionally rewarding by the prestigous image of those glass-bulbs

no way - good converters are expensive in single quantities and are usually SMD parts which require special tools and custom made circuit boards.
this is the cheapest box I know
http://www.thomann.de/gb/sm_pro_audio_ao_8.htm
otherwise an Adat with damaged/worn out tape drive can be found between 40-100 Euro on eBay, but unless you specially like it's 'sound' it doesn't really make sense compared to the box Gary suggests
