Ruby6V6 Matched Amp Tubes Matched Quad
Independent shopping perspective
The Korena take
Ruby’s 6V6 matched quad supplies four 6V6GC beam-tetrode power tubes for replacement work requiring a full matched set. The tubes are described for 15–22-watt amps and are positioned as a premium replacement option for Fender Deluxe and Princeton models, Marshall DSL15, Orange Rockerverb, and many low-wattage boutique amplifiers. Transconductance and plate-current measurements are labeled on Ruby power tubes, providing the matching details that support long tube life and optimal performance.
Strong match
Who this is for
- Replacing four matched 6V6GC power tubes in an amplifier that requires a full quad.
Consider the trade-offs
When to look elsewhere
- Amplifiers that do not use 6V6GC power tubes.
