Description

This BUY-IT-NOW auction is for a set of 10 each USED "acceptable limit" replacement tubes for the 12AU7A tubes as used for audio power. These tubes are built to mil specs and are premium replacements for the 12AU7A tubes. Each tube was tested on a Precision Apparatus Company model 612 tube tester for any shorted or open elements, intermittents, filament continuity, quality of emission percentage, or any other defects. Sorry, but due to parts swappers, I will not take any returns or exchanges. All tubes will be contained in a standard 1 inch X 1 inch X 3 inch generic tube box (which will help prevent breakage) with data results printed on the box as shown in the picture. PLEASE READ : Due to the rising cost of gasoline prices, and the fact that my nearest carrier is the USPS Office located over 17+ miles one way, parcels will be sent out only ONE DAY per week starting on August 1/2022. This applies to all parcels sent by USPS, UPS, FEDEX, or any other carrier. Orders must be received by Thursday midnight to be shipped on the following Saturday. All orders received after Thursday midnight will not be shipped until Saturday the following week. Holidays, other carrier closedowns, or any related vendor problems (sickness, floods, fires, or vehicle, to name a few) could cause further delays in the shipping process. I ship via FIRST CLASS shipping to lower 48 states to retain my prices at 'ROCK BOTTOM"! IF YOU DESIRE PRIORITY 3 DAY SHIPPING PLEASE NOTIFY ME AND I WILL REQUEST AN ADDITIONAL $4.00 THRU PAYPAL FOR THE PRIORITY EXTRA CHARGE.
