I have many Matched pairs of Amperex Bugle Boy ECC88/6DJ8 tubes made in Heerlen, Holland.
Famous Amperex sound: warm and rich with 3-D soundstage and zero driness and full bass.
As you may already know, these wonderful sounding old stock Amperex Bugle Boy 6DJ8 tubes tend to be noisy and/or test low.
Test very strong just like NOS or close to NOS.
Low noise and microphonics to make sure they will work with no problems in your system.
$35 for one tube.
USPS Priority Mail Shipping with Tracking within US will be $9.
I will accept Check or USPS Money Order as Payment (no Paypal).
Local packup is welcome.
