Product information “EL84S-STR Blackplate Tubes Premium Matched”
The all-new TAD-tubeline – the Blackplates – show a top performance because of a very stable thermical heat dissipation resulting in brilliant longevity. Tonally, you can expect a sweet breakup, warm and musical mids with an overall NOS-character, following and paying hommage to the legendary designs of the golden age of tube manufacturing.
Tested, selected and matched by TAD in Germany!
⦁ very detailed and defined tone
