Alles over TAD.
At VDS instrumenten you will find TAD preamp tubes such as the ECC83/12AX7, 7025 and 5751, including low-noise and Highgrade versions. For the power section we stock matched sets of 6L6GC, 6V6GTB, EL34 and KT66 in Blackplate versions, among others. There are also rectifier tubes such as the GZ34, 5Y3 and 5U4G, plus a solid state rectifier as an alternative. If you work on amplifiers or guitar electronics yourself, we have Orange Drop 225P and Mustard capacitors, single and in 10-packs. This way you can buy TAD tubes for maintenance, repair or a different sound.
Replacing tubes calls for the right choice and sometimes a bias adjustment. If in doubt, contact us before you order.
