    Over the past 20 years I have supplied over 2300 control boards and kits to tube amplifier builders around the world - literally, from Alaska to Antarctica.

    However, 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.

    Until then, sales will continue as normal (see for ordering details and the downloadable user manuals).

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

    Would such a board be an upgrade to an Emtron DX-2SP ?

    Probably best to contact him directly through his website...

    Completely out of the question. Why? Ian's boards are designed for a homebrewing project and not concerned about miniaturizing the kilowatt. In other words, for best practice don't build into a small space, so that everything needs to be designed like a tight fitting glove.

    Not a problem for me, as I'm home-brewing a triode amplifier and have just finished assembling his triode board.

    I have 2 of his triode boards that I will not be using. I had ordered a set of tetrode boards and received a pair of triode ones. Too expensive to ship back. Let me know if you want one.

    Email Ian. You have my boards and I have yours. He sent me new ones and didnt ask for the other back. He said he was prepping both our orders at the same time and sent me your tetrode board and sent you my triode boards by accident.

    Sent him a note. Thanks for the heads up.
