The new TAD EL34-STR REDBASE™ developed completely from scratch! Yet, the results are phenomenal. In the tradition of the legendary Telefunken EL34, the TAD EL34-STR REDBASE™ provides a gorgeous, dynamic and amazingly open in-yer-face tone with just the right amount of angriness. Expect a clear, harmonic and open top end, a lovely spot-on midrange, with vocal low-mids and a great bass response as you would expect it from a TAD EL34. Extra rugged glass envelope, golden control grid wire, two especially large cooling grids and special high-precision construction with smallest tolerances guarantee for maximum stability and reliability.. The TAD EL34-STR REDBASE™ differs from other EL34 tubes in particular also by the extreme quality control in the production and the special formatting of the tubes by TAD in Germany before the actual matching.
