Also he's stated that you may not get the one in the advertisement, so although the picture is of a new looking one, you may get a blackened and half-melted dud in the worst case scenario - though I'd hope to have a bit more faith in human nature than that...

The YC156 are available as tested (and guaranteed) pulls for $380 
although I've forgotten the source...I'll do some searching as I 
*must/should* have a record of it around here some where.

The only complaints I have about the tube is the size 9" tall, weighs 
over 9# and the long warm up time of 6 minutes.  I complain about the 3 
minutes on my current amp.
