$100 ,...  I have a almost new pair of Pearl Cryo 6n1p's, ultra low noise version.  They have ~50hrs. on them. Were bought new (by me) 2 months ago.  These are fantastic sounding tubes in the Decware amps. The best I have found.  I've rolled 6dj8's, 6922's, 7dj8's, 7308's and 6n1p's.  I found the Pearls to sound the best and 7308's (Siemens Steel pin) were my 2nd choice.

I just sold my Rachael and have no other gear that uses this type of tube, hence the sale.  $100,  PM/email me if interested,...
