I have four Telefunken 12AX7A tubes for sale. All have the
diamond imprint on the bottom between the pins. The Telefunken
logos are fair to poor, but that is usually the case since they
rub off rather easily. They are all strong and BALANCED from
side to side. $26.00 each. Buyer to pay for shipping via USPS
"Priority Mail" which will be $5.00. Canada may be higher. See
my excellent ebay feedback under the name "Skyline7576." Thanks.
