The use of DHT in our DACs became a hobby in itself.

That’s why we prepared some information for you concerning tube rolling, tube types and general guidance in thr DHT world (which stands for Directly Heated Triode)

There has never been a tube like that! LampizatOr is very proud to present: “Łukasz Fikus 6th Anniversary 45 DHT Mesh Globe Triode”. Created by Emission Labs for LampizatOr, better

than anything they ever made. An instant collector’s item!

  1. EMISSION LABS -  ON THE CUTTING EDGE OF TUBE QUALITY


  1. 45 Triode specifications

  2. Mesh anode style for best sound

  3. Limited production-custom run of 50 pairs for 50th Anniversary

  4. Made for LampizatOr Golden Gate DAC

  5. In addition to factory tests we conduct a musical test in our listening room with

  the Golden Gate DAC.

From early 2015 we started using also KR AUDIO tubes also known as KRON after the last name of Mr. Kron, who was behind the factory and the tubes.

Lampizator Anniversary Edition Special KR5U4G rectifier.

Introducing: the Limited Edition, one time special production run of the rectifier tube that is our best attempt to offer a very unique rectifier for our Golden Gate DAC as well as our Lampizator Mono Block amplifiers. This rectifier has 5U4G specifications except that it has the best vacuum in the entire industry so it lives much longer than any new rectifier money can buy. This Anniversary edition has unique glass shape never used before so it is easy to distinguish from regular 5U4G. They made for us only 50 pieces and no more is planned . You can get them through Lampizator distribution network.

The KR5U4G has cathode with bigger active surface with higher emission capability. We use original carbonized nickel anodes, where the thin graphite layer is also on inner side of anode plates. This minimizes reverse flashes (backward current from anode to cathode), because of high work function of carbon. Tubes are exhausted on vacuum machines longer then mass produced tubes, so we get better vacuum before flashing barium getters. Then the tubes do not need so long burning-in, which would be done at the cost of lifetime.
