Just check the dates printed on your cash before you go.
If you want mean-azz transistors that will burn rubber and survive, all you need is a time machine.
now that its been quite a few years have. my texas star 500 with deis has been running flawlessly so far. the output transistors are dei and i know they dont have a good track record. We were seeing a higher and higher rate of new tubes that were "duds" as the size of production runs would shrink smaller and smaller. i want to click the order button on a new texas star dx1600 sweet sixteen amplifier but im a little apprehensive. Tubes made the last ten years before they stopped altogether were built in smaller production runs. The sweep tubes used in linears for years exhibited this same problem, Tubes made when the television factories used them by the million were just tougher. A part that's been coming out of the cookie cutter for decades. By the time Toshiba had been making the 22 for 20 years you were getting a part that was radically tougher than the specs would suggest.Īnd that's what nobody else can sell you now. Pretty well-accepted rule of manufacturing is that the more of them you make, the higher the quality level tends to be. Quindi la tensione v1, subito dopo la commutazione, sara pari a V V DDRON/(R +RON) e quindi la sua variazione, rispetto all’istante immediatamente precedente, risultera v1 R R +RON VDD. For every ten years they made those parts, they just got tougher. raggiunge esattamente il valore nullo, poich´e il transistore di pull-down all’uscita di tale NOR avra una resistenza RON diversa da zero. The logo changed to the bold upright block-letter font in the late 80s. If you see one with a 'cursive'-looking "Toshiba" on it, that one is really old. The first year or so they were in production, they seemed easier to pop. The Toshiba transistors were incredibly tough. The harder you push it, the sooner it breaks. I will occasionally ask a customer how much "KBK" he wants from his box, explaining that this will dictate the power level he can get. How hard you stress it dictates the service life. Come interruttore, il transistor permette o impedisce il transito della corrente allinterno del circuito elettrico: il sistema può dunque assumere il valore binario di '0' o '1', permettendo di realizzare i circuiti elettronici digitali alla base della logica booleana. A motor that wins quarter-mile races won't go 150,000 miles between rebuilds.Ī machine is a machine is a machine. The stresses you put on machinery will dictate the service life. New transistor could cut 5 from world’s digital energy budget: Design also poised to save space, retain memory in event of power loss - ScienceDaily. Should it go a whole quarter mile before it blows up? Or maybe two or three quarter-mile runs? Or a 50-lap round-and-round race?
