I gave Brent Jesse a $300 budget for a quartet of tubes when I had a Freya+ on back order, but I ended up with a Kenzi instead. I never even opened these tubes. Brent suggested military RCA made VT-231 type 6SN7GT for gain stage, and the short bottle Ken Rad early 1950s type 6SN7GTA with the side mounted getter for the output stage.
Again, unused and matched by one of the most reputable sources for tubes.
$284 for the tubes, I’ll pay for shipping. Venmo is fine, or a check from established member also fine. Happy to ship after the chaos of the holidays if you prefer.
New Old Stock original box & white box. Very fine sounding, very rare blackplates from the 1940s, made for US military. These are the very desirable VT-231 type with the grey glass, and all are military stock, originally parts for radar equipment. These rival the RCA 5692 redbase in quality, and are just as scarce. Carefully matched internally and from tube to tube. All VT-231 RCA grey glass stock, some labeled for the US Navy.
Thanks again for the heads up on this distinction. I am tempted to keep them for a Lyr 3 one day but I’m already up to 4 headphone amps since I started this friggin’ hobby
