About GU74B Tube Availability

Company Statement About GU74B Tube Availability  |  01-Dec-2023

According to our company's policy for transparency, we want to share important information about the future of our well-proven tube-based amplifiers ACOM 1010, 1000, and 2000A. These amplifiers, built upon the GU74B tube from Russia, face a shift in their sourcing due to prevailing political and economic circumstances. Regrettably, the use of Russian tubes in our amplifiers is no longer possible, owing to EU restrictions on imports.

There is no cause for concern. We have good news, and the future of our amplifiers is bright.
We worked hard in the last two years, and now we have a NEW 4CX800A tube – a functional replacement of the GU74B.


Starting from January 1st, 2024, we take profound satisfaction in production the amplifier models 1010, 1000, and 2000A exclusively with these NEW 4CX800A tubes. We strongly encourage you to take prompt action and seize the opportunity to place an order for your new amplifier today.
Also, starting January 1st, 2024, we will only offer our NEW 4CX800A tube as a spare part and a replacement for a GU74B tube.

The new tubes 4CX800A are produced in China by our long-time supplier and producer of 4CX1000A tubes. ACOM invested a significant amount of money to develop our tube testing processes and special tube testing measuring equipment. All new tubes are tested in the factory with the ACOM's developed and manufactured equipment to our quality and technical requirements.
