Any need for these tubes ?

I recently came across a small number of tubes, all NIB.

One number i seem to have several of is a 6MA6 tube. This looks like a 6BK4 tube, as it is a shunt reg. I think i have 4 or so I would part with.

Also several 6LR8 tubes--maybe 4 of these too.

And maybe 4 6LB6 tubes too..

And a few 6LJ6 tubes too.


All tubes are NOS NIB.
