Right in time for the 5th anniversary of his amp of fame, the El-34, Thomas Reußenzehn of Reußenzehn Tube Power introduces the Mk3-version of the single ended class A amp. Newest and most important feature is the possibility to muscle up the former 10 watts up to a strong 19 wattage, and when used with 6550 tubes, even up to 21 watts. With this, you can now use this tiny but powerful and first class sounding amp in a band kontext without any problems. The El-34's power section can be stuffed with the tubes of your choice – on the fly, without correcting the BIAS. Either EL-34, 6L6, KT88 or 6550 – everything goes! The price of this tube cube is neat as well: €849.
