SOLD!. Supratek Dual preamplifier in perfect working order and excellent cosmetic condition. Originally bought as Cabernet was later upgraded to Dual in Australia by Mick Malone. Kevin Covi (Mick's partner) upgraded it again in New York to be used with 71A and 37 or 76 Nos tubes which makes the sound more natural. This upgrade was made in January 2009. The total cost of the upgrades was 00. The preamp is sold with the following NOS tubes: One pair of RCA71A, one pair of RCA37, one pair of RCA6L6G and one Philips Miniwatt GZ34 metal base. All these tubes are like new and tested perfectly in my TV7 tube tester. The preamp comes also with one pair of EH6922. Although I'm new in this place I have 100% positive feedback at eBay with 388 votes. My nickname at eBay is jpms02.
