Tube Amp Doctor 12AX7 / ECC83 Redbase Premium Selected Preamp Valve

TAD buizen, degelijk betrouwbaar en goede sound! Ik heb diverse huizenversterkers (Fender twin, bandmaster en vox ac 15 en 30) en ter vervanging van de pre-amp buizen al diverse 12ax7 buizen gebruikt. Belangrijk is dat de buizen getest zijn op ruis en dat ze geen microfonie geven. Dit laatste is erg irritant bij het spelen, deze zognaamde rinkelgeluiden zijn erg storend. Er zijn goede en slechte buizen op de markt. De laatste jaren vertrouw ik op de TAD, hebben mij niet teleurgesteld. Tip, voor het wisselen van de buizen altijd de versterker minimaal 24 uur ontladen van elektriciteit.

Tube Amp Doctor 12AX7 / ECC83 Redbase Premium Selected Preamp Valve

Buis in mijn Hartke HA3500 ingezet. Klinkt net weer iets dynamischer dan de originele buis. Ook is de volume verhouding tussen solid state en tube voorversterker beter. Ik ben tevreden.
Vervangen was erg simpel.
