After 20 years these products are nearing the end of their design lifetime and some parts are becoming harder to find,
so we are giving a whole year's notice that the Tetrode Boards and the Triode Board will be 'retired' from the market by the end of 2019.

Support for existing customers will of course continue beyond that date.

 


WARNING - the "G3SEK Triode Boards" and "G3SEK Tetrode Boards" advertised on eBay by Eastern European sellers are FAKES! I will only provide help and technical support for my own genuine boards.
