soundbrigade said:What tubes?? Oh, it's you Wavebourne, then my guess is GU50 ...
Right.
GU-50, 6N6P, 6F12P. 6E1P
If you are interested in the GU-50's, I have a bunch. Else I guess you can finmd them here and there: eBay or better still check Röhrentechnik or Frag Jan Zuerst .

Re: Re: my DAC
PCM2707
PCM1798
tube buffer for output
4 OPs performed I/V convertion
Only USB, doesn't support 1394.
I have another type support 1394.

You bet! ... more pictures? Tech details? ... got USB / FireWire I/O ? 16 or 24 bit?

alpswolf: " I have another type support 1394. ..."
All right! Show me a kit for FireWire and I'll be buying immediately.
It appears that you have a kit that has all of the surface mounted chips already placed, yes?
Happy about that! My old tired eyes can't do SM anymore, but I can still swing a mean iron for the old technology resistors and capacitors ... Where do I find a schematic?
Is this 24 bit capable?
