Description

Designed to the highest industrial standards for Hewlett Packard, these vintage 12AU7A dual-triode vacuum tubes were made in Great Britain by Amperex. They were removed from laboratory grade HP measurement equipment. Each section tested 95+ on a TV-7D/U where the minimum value is 56. Each order is for a single 12AU7A. Promptly shipped to your door with USPS Ground Advantage, Priority Mail or UPS, your choice. The eBay International Shipping Program can be used for overseas orders. You may also select USPS International shipping which may be less costly. I offer combined shipping with my other items when practical. Put the items in your cart, commit to buy and ask for an invoice. This can only be done in a web browser, not an option with the mobile app. Carrier delivery dates are estimates. Unusual circumstances (such as traffic, staffing fluctuations, severe weather, natural disaster, changes in carrier route, drought, bandits, filibusters, etc.), can cause deliveries to be delayed. If you require special shipping arrangements please contact me before purchasing. From a smoke free and pet free setting. If you have questions or would like other photos, just message me.
