Purity Audio Ultra GT Series
Active/Passive Tube Pre-Amplifier Dual Mono Power Preamp/Power Supply
NO PCB Boards, This is Hand Crafted Point to Point Made in the USA. If you want a Truly Musical Sounding Pre-amp this is the one to get. It has served me well and regretfully up for sale due circumstances.
Priced to sell.
For On line Specification: http://purityaudiodesign.com/ultraseries2.htm
Iv been trying to downsize my setup and as you can see am selling off all my Audio Gear, Speakers, Amplifiers, Cables, Grounding Conditioner and my home theatre setup. My change of plan is due to personal life style changes. I just had a baby boy and we are in the processing of moving into a smaller new home. Therefor I no longer have a dedicated listening room and cant justify keeping anything for my audio anymore.
Here I have for sale is a Used Purity Audio Tube Pre-Amplifier of which I consider world class as it bested my previous VAC and ARC Pre-amps by miles.
Unit is exactly 3 Years old. Excellent Condition Electronically and physically except the minor labels/Stickers which are starting to wear off and the screws which are showing oxidation seen in the pictures.
I have put about 700 - 800 hours approx. on this unit. The Original Tubes are included but honestly id recommends buying new tubes.
Electronically the Pre-Amp is dead quiet and in excellent working condition no issues have ever been recorded. The unit just works wonderfully and probably one of the most flexible unit money can buy. Not only can you run it Active you can also run this Passive with volume controller coupled. It has grounding lift switches. HT Bypass which I paid extra for at the time but is now included in all Purity Audio Preamps.
This unit has been further upgraded to Vcap CUTF and Further Bybee Purifiers in the Power Supply and Bybee Music Rails in the Pre-amp. This is the same Specification Bill Baker has on his Ultra GT Series in all aspects except my Unit does not have the Silver Dueland Capacitors bypass otherwise it’s the Same Spec as the GT Series.
Since am willing to accept a huge financial loss on this unit I have priced it very fare and will accept any reasonable offers.
Unit is wired for 230V but this can be easily changed if shipped directly to Bill Baker In the USA. For USA Buyers.
