This is a list I've been compiling over the years, culled directly from the hard work and resulting posts of those here that know what they are doing. I just filled in the blanks as I went along, using the suggestions that were researched here by those a lot more talented than me in this arena.

Because of this, there may be errors or some inappropriate subs depending on what the circuit needs, but for the most part I think it might be a pretty decent jumping-off point for folks that are looking for substitutes.

So far it has helped me out a few times. If it is wholesale crap Last edited: Jun 9, Uncle Bambi , Mar 6, Messages: 2, Location: Costa Rica. I grabbed the lists and made an excel document, removing duplicates. Remember that this lists are just guides, can have errors, check always the datasheets and the transistor function on the circuit in order to find a proper transistor replacement.

There are a few errors with some part numbers and such, I'll help with correcting them when I have a free moment. I did find:. Hipocrates likes this. Another thing about generic transistor replacement lists is the replacement part isn't always good for every application.

In one application of the 2SC in a low current low voltage preamp circuit, the use of a KSC might be right, but in a different preamp where the current was higher and the 2SC was fine because it handles more current, the KSC might fail because it only handles very low current. So, there will be those who say "a generic transistor substitution list is crap" and this will part of their argument.

One way to avoid the list being a bad thing would be to carefully and repeatedly say "these substitutions are a starting point only. You need to examine the replacement device and its specs for your specific application to validate it is right.

This list has helped me narrow down the candidates, but I need to understand my schematic, understand the operating conditions of this device in that circuit, and look up those in the data sheet for the substitution device. And ask AK in my own thread. While we're at it It has additional info on bad transistors and the like, gathered from posts around the site by well-known members.

Next thing I need to do if check all the PN's and make sure they are still available or that they haven't changed. Hope this helps someone, it's the biggest list I've seen around.

Sub List. Messages: 4, Location: Mass. Replacing transistors can be a minefield. I then got oscillation on the output. I had to put in bigger VAS capacitor to slow things down. The new transistor had a much higher gain than the originals. Messages: 2, Location: Close to Alkmaar, Netherlands.

Hi guys! Is this one will be good to substitute the 2sa? Thanks a lot for any answer!! The parameters of the ksa look mostly good as a replacement for the 2sa Can you show us the application schematic? Here it is. I got no sound of the left channel and very low distorted on right channel. The Q is visual destroyed - half of the round body is missing and the resistor next to it is blown.

Thanks for the answer!! I got the schematic from hf engine. Messages: 57, Location: Hertfordshire, UK. I think dlucy is right, if one transistor of a complementary pair blows especially in the way you describe, I think you should change them both.

Preferably for another substitute complementary pair if the originals are not available. Hyperion , Jun 9, If your application needs more than that, up to mA, then you'd want the KSA So there are two 2sa driver transistors and im going to change both and the related resistors as well.

Also, there are two caps related to it but I have only Vmeter and one msr meter which don't know why i bought it for How to test this caps? Thanks to both of you guys!!

Thanks a lot! If you don't have a "cheap component tester", then is just test with an ohm meter. And replace any electrolytics. You must log in or sign up to reply here. Show Ignored Content. Share This Page Tweet. Your name or email address: Do you already have an account?

Although I don't really agree with their statement: " If you put a standard 2SCR into a TR in place of the noise selected part the sound completely changes. Maybe I accidentally, by luck placed a shitty in Q35! I also doubt: "TR is pure analogue and the transistors had to be carefully selected and matched, otherwise every would have sounded different from each other, not at all a satisfactory state of affairs if every new TR in a music shop sounded different from the others.
