A number of different power valves can be fitted to the Merlot. It is one of the great strengths of an open valve amplifier, that different tubes can be "rolled" for different tonal balances. In this instance a matched pair of JJ KT88 Blue Glass have been fitted. This has increased the low end weight and brought the mid-range forward slightly. Apart from the different tonality the Blue Glassed JJs look stunning. Many other valves and speciality tubes can be rolled into the one basic power amp. Have a favourite power tube which has the same pin outs and specs as a common KT88? Then roll it into a Merlot. Plug and play-your way!
