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.
