pre standard preamp

PMA · 4th December 2003, 09:39 AM

Just two photots of the new preamp. Balanced/unbalanced inputs and outputs, outputs independent and able to drive 50 Ohm load.

The second one ...

Very impressive indeed!
Can you please give us more details? What kind of preamp circuit did you use? Where did you find the printed circuit?
The enclosure is really beautiful, it looks like solid aluminum. Where did you get it?

My best compliments for your nice work!

Waauuuwwwwwwwwwww.. that looks beautiful.. Where did you get that alluminium(?) case ...

Can you tell us something about your circuit/topology?

Have fun,
Thijs
