THE GREAT MULLARD MAGIC BLOG — PUSSY TREATMENT OF VALVES

Last time I described the exciting treatment that Noctode, our cat provides for the valves I have on sale. It has long been my opinion that Pussy treatment of valves gives EXACTLY IDENTICAL audible effects to that provided by cryo treatment of valves, but ho-hum, that’s a very subjective claim so I sought a more scientific unbiased opinion. To this end, I lobbied a famous reviewer from the hifi comics, sorry magazines, to do a blind comparison on my behalf. The day dawned and the critical ears of  Xmas Cipher-Thicket were called upon to perform.I tried to do the best I...

 We bring you our latest exciting new development. Some of you will be aware that post manufacturing treatments of valves is currently en-vogue. I have read with interest just how beneficial cryogenic or ‘cryo’ treatment of valves is purported to be. Allegedly, the stresses induced during valve manufacture affect electrode structure tolerances within the valve and cryogenic freezing relaxes these – permanently. As a scientist, I understand that many of the metals used in valve manufacture such as Copper, Molybdenum , Nickel and Tungsten are transition metals. I am however, unsure how a transition metal’s ‘electron ship in a cation...
