Where can I find suitable replacement tubes for Orange guitar amplifiers?

For Orange tube amplifiers, suitable and robust replacement tubes are especially important. This applies, for example, to Rockerverb 50/100, AD30, TH30, OR15 and Rocker 15. Depending on the model, EL34, EL84, ECC83 / 12AX7, ECC81 / 12AT7, 12AU7 or, in some series, also 6V6 are particularly interesting. Orange explicitly describes the AD30, TH30, OR30 and Rocker 15 as all-valve amps with EL84 power stages; in the Rockerverb, EL34 are among the classic power tubes. With Orange, matched power tubes are especially useful so that output, matching and reliability suit the respective power stage. This is particularly important for models with EL34 or EL84 configuration if the amplifier is to run reliably and remain tonally coherent. Many of these types are also available from BTB in premium matching quality.
