Technical Bulletin TB-00

About Burn in

by: jac van de Walle

Probably all manufacturers look on the web sites of others, to see what they have to say. And so do we. But it gets curious to see fragments of our technical information simply copied on competitor's pages, or just the core of our message with an altered text.

From the first day we started, we published a clear burn in instruction for 300B tubes, in that particular way it was written (by me). Not because we know it so much better, but because people were asking often.

So yes, we are pleased to read recently on the Western Electric website, their burn-in advice for 300B tubes, which to my opinion has some similarity with our own procedure. This is a simply good to see.

We are less pleased to see our burn in instruction blatantly copied by a European competitor. No, that is not the way to do it. But even so they do not write things that are wrong.
