Which tubes are particularly suitable for Conrad-Johnson if the unit is to run with a tonally balanced and close-to-original sound?

With Conrad-Johnson, the correct tube configuration depends strongly on the respective series. In the power amplifiers, models such as Classic 62 and Classic 120 are good examples of EL34 concepts; Conrad-Johnson describes the Classic 62 output stage with one pair of EL34 per channel, and the Classic 120 accordingly with two pairs. In addition, there are many well-known tube preamplifiers and phono stages from the current and vintage lines. Anyone who wants to equip a c-j unit correctly should therefore always follow the specific model closely. Many suitable tubes are available from BTB in selected quality, and power tubes are also available on request as matched pairs or quartets.
