THE GREAT MULLARD MAGIC BLOG

Well, today, I had an e-mail from an 'expert' on valve vibration.  He attempted to 'correct' my last blog entry  but rather than telling him to buzz off, I thought I would clarify matters a little further in my own 'non expert' way My last blog entry dealt with an example of swept frequency sinusoidal microphonic testing where the gross effects of vibration on valve performance was being assessed at typical conditions potentially found in an accelerating aerial shell. There existed a number of direct excitiation methods of measuring the affect of vibration on valves and for completeness, I will describe just one which is...

Well, look at this,  I have known quite a few dummies, some of them even like valves..... and radios!!!!!!!   But the only Mullard dummy I had ever seen before was my reflection looking back at me from the mirror - haha - that was a Mr. Mullard Magic joke.
