Undoubtedly, when we talk about WESTER ELECTRIC, the first thing that comes to mind is " HIGH QUALITY "! The 418A is a Tetrode, original made in USA, "pristine" condition in its own genuine box and packaging, NOS / NIB. Absolutely interesting tube for AUDIO applications, especially if connected to TRIODO both as preamp stage and as input. Experimenters, "DIY designers" will use this HIGH quality tube as they see fit. Countless information on the WEB. A particularly stimulating example can be found at YS-AUDIO and its esoteric HI-END projects: The Real -TU Line MK2 Preamplifier .
- NB: EACH VALVE IS TESTED WITH OFFICIAL PARAMETERS (SEE LAST PHOTO), AVAILABILITY OF COUPLES AND QUARTETS, TEST ON REQUEST!
