Hi all, For those of you who still use the AX 9909 tubes in the Champ, I have a pair that has full output. If you need them, I am asking $ 35.00 each plus shipping. If you have a GK 400 and need V 70Ds I have 4 NOS and 1 I can't determine if it is new or not. I would ask $45.00 each plus shipping. 73 Jim/W5JO
