If you have any questions, feel free to message me. I package carefully and usually ship within one day via USPS First Class. I also have 100% positive feedback so you can buy with confidence. Thanks for looking!
*** THE TUBES IN THE LISTING ARE THE EXACT ONES YOU WILL BE RECEIVING, UNLESS OTHERWISE NOTED. IF THEY COME WITH ORIGINAL BOXES, BOXES MAY HAVE WEAR. TUBES WILL USUALLY HAVE WRITING ON THEM WITH TEST SPECS, BUT THE WRITING WILL COME OFF VERY EASILY WITH A QTIP AND FINGERNAIL POLISH REMOVER. IF YOU'D LIKE IT REMOVED PRIOR TO SHIPPING, JUST SEND ME A MESSAGE.
MOST TUBES ARE NOT TESTED IN CIRCUIT FOR NOISE/MICROPHONICS, UNLESS OTHERWISE STATED. ALL VINTAGE TUBES ARE SOLD AS IS, AS I CANNOT GUARANTEE THEY WILL WORK AS INTENDED IN YOUR CIRCUIT AMD DIFFERENT TESTERS WORK DIFFERENTLY - I LIST MY TUBES ARE ACCURATELY AND THOROUGHLY AS POSSIBLE***
