Harma Valves
The Harma diamond premium grade valve range is sourced from the best current production and new old stock available today.
The range was established in 1995 and has been as a result of the demand from the professional music industry for a high quality tested valve that will work under the most rigorous conditions.
The valves have been road tested by the major U.K hire companies and high profile musicians. Our S.T.R E34L has been tested and is used by Ben Matthew's of British rock band Thunder for example.
All the valves are tested and selected on our high plate volt tester. This rig runs the valves in real working conditions at high voltages 500 vdc plate and screen for instance for a 6L6 type.
The valves under go tests for cathode heater insulation, heater continuity, gas and are matched via the quitescent current method after undergoing six shifts in bias voltage to ensure perfect curve tracking. This ensures total reliability in touring environment which is why these valves come with one of the longest warranties in the business. 6 months on Pre- amp and output valves.
