I will order replacement transistors for all but only replace those that need The 2SC’s are used in both the pre-amp and main amp, if that. Hi All, total noob here but wanted to confirm something before I actually start replacing these transistors on my Akai GXd. Local electronic. 2SC, NPN 2SC, 2SC NPN Low Frequency Transistor, buy 2SC

It just takes a little time. In addition, some devices are better suited to some types of tasks and toplogies in terms of noise. Well, I don’t use the tuner 2sc4588 it works alright. Damn, I already ordered KSC from Mouser as part of big order and they charge much for delivery overseas.
Guys, I have a whole forest of them on my tuner board: Do you already have an account? KentTeffetellerJul 16, Originally Posted by Mosesmunoz. My only concern is in circuit that use more than 50mA Ic and in this part I wish it was a little more. Probably best 2sf458 do just one channel first and then test it’s ok hopefully and then do the other channel just in case of any errors. Middle of the USA Posts: Transistpr This Page Tweet.
Also I don’t think I will replace those 15 pcs of 2SCs in the tuner. For example Saul Marantz loved to take advantage of semiconductor characteristics and would supply characterized devices as replacements. Contact Us – Tapeheads. It is the geometry of the die that determines what is the emitter and what is the collector.
My issue with NTE is that they seem to often claim substitution capabilities for a device when not the case. Tranisstor are some things that are a little bit more difficult. I have the ‘s that have the flat top and not the slant top ones.
Do you already have an account? Last edited by Ebzen; at Then they post up a substitution list and buyer beware, sometimes they aren’t close and don’t work.
2SC Datasheet, Equivalent, Cross Reference Search. Transistor Catalog
I suppose that there may be special cases in audio signal handling but it is generally safe to say that electrically there are only about five different transistor categories that all transistors can be placed in. Hell if I remember right the replacements for 2SC have reversed pins compared to the older ones. Typically 2SC or 2SD transistors can be found inside the same line to work or if you like to determine the match yourself, you can do that. I concur with Pacific on this as I have used a lot of KSC and they work in more circuits than you think and in other brands as well.
2SC458 – 2SC458 NPN Low Frequency Transistor
Would you like to see your company or site here? For subjects related to tape itself, see the Open Reel subforum under this one. Last edited by Mark J; at Every time I have found one, it has always looked the same – square front that angles back like this: I found this quote from a thread by jpdylon, a really good tech. Of course, one can buy modern s that don’t degrade like the old ones, but they’re expensive in comparison.
Karl vd BergApr 19, If it was built in the 70s, change ’em! Pacific Stereo Sendust for brains.
Find all posts by BarryC I can’t imagine a company will release a product that consistently does not work and still be in business a year later. Even a well versed Technician regardless of education can put together a substitution of 4 to transisto parameters that are needed to find a replacement. Log in or Sign up.
