T-6V6GT-RB-TAD Vacuum Tube - 6V6GT-STR, Redbase, Tube Amp Doctor
The TAD 6V6GT-STR Redbase combines the tonal characteristics of an NOS 6V6GT such as from RCA or GE with the current 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 at the same time a strikingly dense and complex midrange. Especially with this midrange characteristic they achieve a liveliness in tone that only NOS 6V6GT achieve and otherwise remains unmatched. Even when pushed into saturation there are no harsh upper mids, which is frequently the case with other 6V6s. Sweet full-bodied tone with silky highs. Tube Amp Doctor recommends the TAD 6V6GT-STR Redbase for all 6V6 power amps when a full yet freely defined tone is desired. The ideal tube for Fender Deluxe Tweed 5E3 or Blackface Princeton Reverb amps, single ended Class A amps like the Fender Tweed Champ, Vibro Champ, Fender Champion 600 or the Univalve.
