I ust ordered the 7and 9 pin sockets the 7 pin socket fits nicely in the hole not tight but alot better then i expected as for the 9 pin socket its about 1/32 smaller then the 7/8 dia. tubing not bad also . Maybe will do 7 pin sockets like on picture glue
ing pin saver to socket so its hopefully sturdier.And today got my Westinhouse 6BQ7A tubes good thing i bought 20 i broke 2 of them after i cut the pins off i used my Dremel to remove the balance of the pins and i guess vibration broke them from now on its going to be the good old file. Very nice sounding 3d like for $3.00 each will be even better when i dont have to butcher them anymore .
