I purchased these 6SN7 grey glass VT-231 tubes thru one of the more reputable Audiogon tube dealers, but I had sold my Berning amps, so I have no use for them.
I am asking 100.00 for the VT-231's
Also have a pair of NOS RCA grey glass 6SN7GT for 100.00
One matched pair of RCA clear top 6FQ7/6CG7 for 60.00
