I run AVVT as well as Sophia Royal Princess and Western Electric 300Bs in my systems (Cary) and have a calibrated Hickok 752A that tests 300Bs. I've been around here for 23 years and if you want to pay return postage I will test them for you and get them back in the post the next day. I am in Seattle. You would want to double box them with lots of bubble wrap.
Cheers
