I just received the Woo WA6 along with the tube upgrades, which includes a pair of Pinnacle 6DR7 power tubes as an upgrade to the Tung-Sol 6CY7. Anyone heard of Pinnacle vacuum tubes? There are no markings either on the box or on the tube to suggest where they are made. Are they a good tube?
Thanks
