Product Description

Brimar 6SN7GT/CV1988 - Made in England. Smooth mids with a greater sense of depth, and slightly relaxed on top. Packed in NATO military boxes. As is typically the case with 6SN7 types from this era, these are not low in microphony. In fact, we are completely out of Gold and Platinum grade. This means the Brimar CV1988 is not suitable for use in preamps or phonostages, so if you're looking for a warmer tube for these applications, try the Sylvania 6SN7GT or the Zalytron 5692 instead. Price is for a single tube.

Very limited stocks on hand so we will confirm what we have available prior to processing your order.

Gold grade - Low noise and microphonics with a triode balance typically between 15% and 20%, but may be higher depending on available stock.

Please note that in some sensitive circuits, this grade may still go "TING!" through your speakers if you tap the preamp or flip switches. That is normal with NOS 6SN7 types and should be expected.

Driver grade - Lowest noise but not the lowest in microphony. Triode balance will be similar to Gold grade.
This grade is only suitable for use in the driver stage of an amplifier, or the output/buffer stage of a DAC or CD Player.

Great Tube

Posted by Chuck

Very smooth and detailed with great control across the frequency spectrum.Bass is deep and powerful with excellent mid-range and high frequency extension. Use these with a pair of Bugel Boy 6DJ8's in the pre position. Used these in my Cary SLI-80F1 and they did the trick at smoothing out the high frequencies of my Focals. Very quiet and not microphonic at all in my Cary. Highly Recommended if you need to tame a bright system .
