I do combine items when and if possible or practical
This Tube Is New In Original Box
Having collected ~83000 tubes since 1955, I just can not
remember detailed history of my tubes. However, I can and do
test and FULLY GUARANTEE all my tubes ( Including NOS & NIB
) that I offer for auction on eBay.
I usually ship immediately upon receipt of payment. Enjoy your bidding! LOCxGUGA
