Here’s the statement from EHX founder Mike Matthews:

On March 11, 2022, Russia imposed a ban on the export of some 200 goods in response to the sanctions imposed on it over the current conflict in Ukraine. We have confirmed that the ban applies to our seven brands of Russian tubes. Currently, the ban is set to remain in effect until the end of the calendar year.

Given this export ban, we will not be receiving any further tube inventory for these brands. A myriad of pressures — including continued strains on the supply chain, escalating internal expenses, mounting inflation, and an ever-evolving legal landscape (particularly in light of the Ukraine conflict) — have created a very fluid and ambiguous environment. Until we can properly assess the impact of these factors, we will not honor any new orders or ship any more Russian tubes on back order.

The brands affected by this ban include Svetlana, Sovtek, Mullard, Tung-Sol, Electro-Harmonix, EH Golden, and Genalex Gold Lion.
