sold my Kondo amp & am therefore releasing my hoard of tubes collected over the years:4 x USED Philips Miniwatt Holland GZ34 (tV1, metal base, holes in plate, 1956)
excellent condition. purchased as a NOS matched quad from a HK tube retailer in 2008. same date codes & without glass print. I've used this quad in my Kondo amp for roughly 1500 hours. no shorts, leakage or gas. they were tested by a reputable tube store with a highly regarded [AVO VCM 163 tube tester] in April 2014. test results at the position of 120 mA: [tube 1: 100+/100+]; [tube 2: 100+/100+]; [tube 3: 100+/100+]; [tube 4: 100+/100+] (ie. "like new" condition).
price: $800/pair, or $1550/quad 2 x USED Raytheon 6072A (black plate, triple mica, 1971)
excellent condition. a lot more organic & musical compared to [GE 5-Star 6072 with black plate & triple mica, 1953] which I also have. purchased as a NOS matched pair from Champagne Tubes in 2011. I've used this pair in my Kondo amp for < 1000 hours.
price: $260/pair 2 x NOS CSF 5687 (black plate, 1958)
mint condition. very quiet & detailed. purchased as a NOS matched pair from Wen Audio in 2011. was never used. stored away in my Pelican case ever since.
price: $70/pair 2 x NOS Tung-Sol 5687 (flat ribbed plate, 1949-52)
mint condition. I've tried MANY 5687 & equivalents. the 1st generation flat-ribbed plate Tung-Sols are my absolute favorites (extremely seductive combination of tonal balance, drive, & subtlety). purchased as a NOS matched pair from Champagne Tubes in 2011. was never used. stored away in my Pelican case ever since.
price: $450/pair more pics aval. on request.
