Selling my completed ZKit 4 built on a 5"x 7" Hammond aluminum chassis with the following features:
- Upgraded Glow Tube Power Supply
- RCA and 1/8" Input Jacks with Input Selector Switch
- 100K Pot to Adjust the Output Level
This is the same circuit that is used on the ZCD Player and will improve the sound of almost any source.  The preamp will ship with one NOS GE 12AU& and two NOS RCA OC2 glow tubes (One Spare).  The whole package is only $300 with free shipping to anywhere in the USA.

Hello Tubeman:
I am interested in your built Z-Stage at $250. The build looks well done, though I have some questions. Is the front switch a power switch or does it select an input source? I drive a pair of amps via my current passive preamp, and therefore have two output sets. Does yours have two outputs? If not, do you know whether it is an easy modification to install another set?
Can you send a pic of the back side? Are there any other issues I should be aware of?
