Price is for a Matched Pair.    With the TAD 6V6GT-STR REDBASE, TAD has succeeded in combining the tonal characteristics of an NOS 6V6GT, such as from RCA or GE, with modern audio requirements. It is a heavy duty 6V6GT tube, which can handle a higher plate voltage than regular 6V6GT tubes.   The TAD 6V6GT-STR REDBASE shines with the typical NOS "sweet top end" and a strikingly dense and complex midrange. With this midrange characteristic, they achieve a liveliness in tone that only NOS 6V6GT can achieve. Even when pushed into saturation, there are no harsh upper mids, which is frequently the case with other 6V6s. This tube produces a sweet full-bodied tone with silky highs.   We recommend the TAD 6V6GT-STR REDBASE for all 6V6 power amps when a full yet freely defined tone is desired. This is the ideal tube for Fender Delxue Tweed 5E3 amps, Blackface Princeton Reverb amps, and single ended Class A amps like the Fender Tweed Champ, Vibro Champ, Fender Champion 600 or the Univalve.   Many boutique amp builders use the TAD 6V6GT-STR REDBASE, but the sounds of modern designs, such as amps from REVV or Mesa Boogie, also benefit from the TAD 6V6GT-STR REDBASE.   The TAD 6V6GT-STR REDBASE can replace any 7408 / 6V6GTY / 5992 /VT-107 / CV510.
