So voltage rating is not an issue. This is part of the output circuit on a solid state guitar amp Marshall Valvestate that I messed up on. I have some BC and L stock. Does this forum have a “PM”. May 3, They work by then shunting some of the darlington base drive signal to earth in overdrive conditions.

First let me say that I have never worked on this particular model, so anyone with personal knowledge is welcome to chip in pun intended here. Click here to register now. You May Also Like: I will save it for future reference.

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. The pinouts are the conventional way looking at the transistor from the wire end ie up under it as it is mounted on the board.

They form part of the protection circuit so if you are refurbishing you can remove them to get the main parts working properly. Another question is looking at the data sheet for transistors what does the Hfe mean?

If you cannot find it I can tell you the measured value of any I send if you wish. Just have a look at this. No, create an account now. So the other transistors may be fine as they will not see the full rail.

Discussion in ‘ General Electronics Chat ‘ started by sweatykAug 14, Ras thanks for that link. To participate you need to register. I feel really dumb here and way out of my league with the knowledge that most of you guys have.

Is there much difference and will it work in place of vatasheet BC? Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at I didn’t see one unless I’m not looking too hard. Here’s a scheme for 9 voltages from 2. The transistors in question are not actually necessary for the operation it should work perfectly without them.

Replacement Transformer Started by ncag Today at 7: Welcome to our site! I am also considering just biting the bullet and go to ebay to get the exact ones so I know it will be right. As RAS has dtaasheet you have many possible replacements, the question is why did the original fail? For a better experience, please enable JavaScript in your browser before proceeding. They will never see a greater voltage than the BE pedestal voltage if their respective darlington, TR8 or TR10 which will be somewhere between 1.


I have measured some and the actual breakdown voltage is for the BC and 75 volts for the BC I have an order with Mouser Electronics and this is the last item I need.

In particular they are higher gain, lower noise transisto. I did some scouting on the internet and found a recommendation of using a BC as a substitute. Aug 15, 7. The first reply in this thread has your answer!

Both transistors come in a variety of pinouts depending upon end letter so you need to ensure a match. Aug 15, 9.

The “PM” feature is not in the list of options when I left click.
