Both transistors come in a variety daatsheet pinouts depending upon end letter so you need to ensure a match. Being you have way more knowledge with this I will trust your judgement.

When looking for a replacement or equivalent how important is that number?

No, create an account now. That only leaves the issue of pinout to resolve. On your drawing of the By continuing to use this site, you are consenting to our use of cookies.

Trabsistor had neglected to fully read the terms and agreement when registering here and didn’t see that. However I do want to learn the reasons why on the choice to further my understanding of how these components work.

Discussion in ‘ General Electronics Chat ‘ started by sweatykAug 14, Unfortunately obsolete items come at a premium. Amplifier repair Posted by lubnaan90 in forum: The 2SA is the complement of the 2SC Trnasistor am attaching the schematic.


You should have an email to reply to.

The BC has a current rating trannsistor mA and a frequency Ft of MHz, whereas the has a currrent rating of only mA and and Ft of MHz so you need dtaasheet check the application here.

Aug 15, I’m replacing a BC transistor and of course transietor are obsolete. I did some scouting on the internet and found a recommendation of using a BC as a substitute. Welcome to our site! In particular they are higher gain, lower gc212 types. Last edited by a moderator: I didn’t see one unless I’m not looking too hard. Here’s a scheme for 9 voltages from 2. You like Yapanese parts? Current rating may be another matter and why Marshall went for a mA transistor rather than the more usual mA small signal job, so we should stick with that.

It worked prior to this with the exception of the reverb. Aug 15, 8. Frequency rating and gain will also not be a critical issue in this application. Amplifier repair Posted by dreamspy in teansistor My BC measures 96 volts at breakdown. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

Is there much difference and will it work in place trsnsistor the BC? First of all hello to everyone and this is my 1st post here. Pioneer Elite vsxtx water damage no power Started by Watin 34 minutes ago Replies: Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Now did you say you are refurbishing this amp? So voltage rating is not an issue. Ras thanks for that link.


They work by then shunting some of the darlington base drive signal to earth in overdrive conditions. Aug 15, 2.

So please check if the centre terminal of TR12 is connected tgansistor the junction of R and R and not D5 or earth, and similarly the centre wire of TR11 to the junction of R and R You will get the feature once you have reached the 10 posts count. I am also considering just biting the bullet and go to ebay to get the exact ones so I know it will be right.
