Original Reference TubesTm
Thank you for your order of AllegroSound Original Reference Tubes.
I have carefully tested these in my lab using specialized equipment and have made every effort to ensure you of the highest performance and reliability attainable.
Inspect your order carefully. If there is any indication of damage, notify the Carrier immediately.
Should a tube fail to perform adequately during the warranty period (typically 100-Day Exchange, 1-Year ProRated), please return it for replacement. (Note: 6111M, AC-701M, VF-14 not installed by AllegroSound are not covered under any warranty).
Tubes which have been improperly used/tested are not covered under any warranty. AllegroSound reserves the right to make this determination. Removal Of AllegroSound logo (where applicable) voids all warranties.
Some tubes have slightly oversized pins, and great care must be exercised during installation and removal, especially in units with tight sockets. AllegroSound is NOT responsible for breakage during installation or removal. AC701 and other flying-lead types require special handling; call for assistance.
Contacts and have been specially cleaned and straightened. DO NOT TOUCH PINS (or the glass on Power tubes) with bare fingers. DO NOT use "contact treatments" on tube pins!!!
Tube MICROPHONES should be run capsule-end UP for lowest noise and longer life of tube and capsule. AllegroSound DataLink XLR-Balanced mic cable should be used wherever sound quality cannot be compromised.
AllegroSound recommends an initial burn-in of 24 hrs before critical evaluation. Long-life tubes, such as AllegroSound 12AX7B, require more. Your feedback via email is appreciated; please note the Make/Model of equipment used.
AllegroSound can supply most types of Audio, Video, Industrial, Transmitting, Receiving, Medical and Special-Purpose tubes at competitive prices. Please email for pricing; include tube Number, Quantity and detailed Application.
