GE 6414 12AT7 E180CC Triple Mica Tubes, Matched Quad, NOS Testing

Hello – I have a matched quad of GE 6414 12AT7 E180CC tubes for sale.

The 6414 tube is used in Manley equipment such as their VTL amps, their 50 and 500 watt monoblocks, their microphone pre-amp and many of their other amps such as the Shrimp, Steelhead, Mahi, etc.

The 6414 has virtually the same specs as the E180CC or 7062. This tube is also like a 12AV7 and will work wonders in any 12AT7 spot, and may be just the ticket if you want to boost the gain of a 12AU7 circuit. The 6414 is hard to find.

This tube stands about 1/2 inch taller than the standard 12AT7. The 6414 is also rated as a 10,000 hour tube.

These tubes have triple mica construction, gray ladder plates and halo getters. These tubes were made in the late 50's/early 60's.

TV-7/B test results: 80/70, 70/72, 75/70 and 70/72. Minimum is 44.

All tubes are tested on my Dan Nelson calibrated TV-7/B or on my calibrated Hickok 539C. All of these tubes have been tested for transconductance, shorts, gas, leakage and life. All tubes meet or exceed manufacturer published specifications of transconductance (Gm) for the specified tube type. All tests are tested twice – prior to the listing and prior to shipping.
