I’ve got a pair of Tung-Sol 6SN7GTB that have 5 hours on them. Purchased from Tube Depot last Fall for $68. Very low noise and microphonics, balanced and matched. $45/pair.
I also have a very nice pair of 9-pin to 8-pin adapters. Nice brass and ceramic, solid. $20/pair. As new.
9-pin to 9-pin extenders - like new as well. $10/pair.
Buy all and shipping is included in CONUS/AK/HI otherwise plan a few $ for shipping on separate items. I’ll absorb the PayPal fees if you don’t want to use Friends and Family.
or best offer for any of it. It’s just taking up space in my tube storage.
