I saw this post together and got excited as I was also waiting for some tubes from W0lfd0g.
When I got home I had a pretty box waiting for me :D
Put in the Tung Sol 7236 and RCA clear top first. Listening right now and it sounds great although A/B comparison at this point will be to hard. I'm still on my honeymoon with my BH Crack :P
I'm saving the famous Brown Base for later. W0lfd0g recommended the 7236 for my HD650s but I was too curious to pass up a good price for the BB.
I also have a few input tubes for later, GE and Sylvania 5936, RCA clear top and a Baldwin (12UA7, not one of the actors)
Oh and good news / bad news, no smoke... So my crack is still go but I'm bit bummed about not getting to try the 2399/5998. Most likely the tube got damaged in shipment :(
Big thanks to Nathan for the tubes.
