ima članak Morgan Jones-a o kuvanju cevi:

e sad, ispada da su cevi poput vitamina, neke termostabilne a neke termolabilne.
da ne trujem više Nixievu temu ali me podsetilo i na još jedno pomodarstvo o kom je bilo pre nekoliko godina dosta reči, o kriotretmanu cevi, o kome citiram autora članka:
The vacuum tube industry today certainly does seem to suffer from more than its fair share of marketing hype. Like the washing-up powder market, the tube market is ‘awash’ (sorry I couldn’t resist that one) with all kinds of nonsense such as cryo-treatment, tube dampers, tube coolers and even rebranding modern manufacture tubes under the names of once great manufacturers – cheap gimmicks that are no subsitute for real engineering. All this nonsense makes purchasing good quality tubes more complicated and difficult than it should be. My advice when buying tubes: invest in tubes from a reputable vendor that checks and matches them on a tube tester and guarantees them or better still, seek out vintage N.O.S. vacuum tubes made by the likes of Mullard, Philips, Sylvania or the other tube manufacturing giants from the golden age of tube manufacture – we’re fortunate that they are still supplies of N.O.S. tubes available and there are deals to be had.

The reality is that cryogenic treatment is not a remedy for inferior materials or defects in tube construction. It simply doesn’t work.
