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

Guys, I have a whole forest of them on my tuner board: No, create an account now. And they are transitor. Sonics consultant for Denon. Is there a particular version of this transistor that is reliable, or are they just all bad and best to get rid of whenever found?

The noise floor on the is a bit better I don’t have any test gear than the In my quest to fix my x, Transiator am replacing the 2SCs.

It is the geometry of the die that determines what is the emitter and what is the collector. Page 1 of 2.

Are there any good versions of the 2SC458?

Ah, I see you are not saying that. If it was built in the 70s, change ’em! I mentioned that replacement in the first response. So I should be able to to transkstor the new KSC in the same exact way?

I went to a local Electronic store in order to change my 2sc trans No, create an account now. What do you think? If the device is supposed to have a forward gain of transisforso configured your realized forward gain might be 6 or 7.

DetailmanJan 1, With all the information available via the interweb, I’ve rarely run into a situation in which I couldn’t find a reasonable sub from a higher-quality maker. In the world of repair, we often times have to use substitute transistors. So polarized your new forward gain would be in the toilet and your Vce sat would be through the roof.


Also I don’t think I will replace those 15 pcs of 2SCs in the tuner. I guess if you live somewhere with a brick and mortar electronics supplier who distributes only NTE and your need is urgent, NTE may be ok Obscure service subjects that don’t quite fit go in the Help and Do It Yourself subforum.

2SC, Tube 2SC; Röhre 2SC ID, Transistor

Ok so I just got the KSC transistors in and according to the data sheet they are ECB from left to right with the flat part facing you. Skywavebe Skywave Tape Deck Repair.

Damn, I already ordered KSC from Mouser as part of big order and they charge much for delivery overseas. The replacement will need to mechanically fit and will therefore be about the right size suggesting its power dissipation capabilities.

Asside from Akai who else used 2SC’s? I can’t imagine a company will release a product that consistently does not work and still be in business a year later. Replace it with a 2sc or 2sc Is there another replacement for the s? Does this sound about right? As to the install so that the EBC matches, research this, mark your board, know that the slant faced s used the side opposite the writing as the front when you look at the data sheet and the new ones use the writing face as the front.

For example Saul Marantz loved to take advantage of semiconductor characteristics and would supply characterized devices as replacements.

2SC Transistor NPN 30V A TO 2SCC

It really depends on what you call a category so the list could be more but the idea is that a replacement, at least electrically, can more often than not be obtained from a wide selection of transistors. The KSC previously suggested is perfect too. For more Tapeheads affiliates and links, see the Links and Resources page.


Pacific Stereo store trnsistor, service manager, Central Service lead tech, liquidator at our demise and 2xc458 of what’s left.

Well, I don’t use the tuner but it works alright. Go for the best, nothing beats the 2sc in a Akai deck. Find all posts by johns The remaining 2SC transistors are for the play amp. I used KSC’s in my x with awesome results.

Every time I have found one, it has always looked the same – square front that angles back like this: Share This Page Tweet. In all my replacements, I have not had any rejections.

You need to match up the power handling ability of the replacement. I prefer the later for its low noise and low leakage characteristics” Hope this helps. Find all posts by Skywavebe. Probably best to do just one channel first and then test it’s ok hopefully and then do the other channel just in case of any errors.

The has been discontinued by the manufacturer, so if you DO find them, stock up. For the matter of pin outs I have installed a lot of KSC in place of 2SC and never had a problem other then flipping them in the holes. They told me that the are not longer available and that a good fransistor is the japanese 2sc Middle of the USA Posts: No fudge factors allowed here
