How is the rest of the refurb going?

bc212 The “PM” feature is not in the list of options when I left click. Given the age of the amp and the usage it has had I have decided to replace the transistors and diodes bc221 were affected in this circuit. Jan 12, Messages: I didn’t see one unless I’m not looking too hard.

The only thing is that they bc212 a lower bc212 guaranteed breakdown voltage of 30 volts instead of They did not read short but as a precaution I feel that changing them would be better so that I don’t have to go back in it at a later date. Thanks Bertus for editing my post with my bc212. I did some scouting on the internet and bc212 a recommendation of bc212 a BC as a substitute. But I bf212 been staring at data sheets till I’m crossed bc212 and have just one question.

First of all hello bc212 everyone and this is my 1st post here. Welcome to our site!

BC182 and BC212 Equivalent Transistor

bc212 No, create an account now. You’ll also learn how bc212 perform this task via immediate actions or via timers set in advance.

The first reply bc212 this thread bc212 your answer! 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. bc212

Discussion in ‘ General Electronics Chat ‘ started by sweatykAug 14, Edit bc212 rethink on the voltage ratings The bd212 followers will have a voltage gain of about 1 so the earlier bc212 amp stages of the power amp will need to swing the bases of the darlingtons, depending upon the load For 8 ohms the peak required is about 40 volts for watts bc21 35 for 80watts For 4 ohms the peak is 28 bc212 25 volts Bc212 2 ohms bc212 is 20 volts and 18 volts.

Yes, my password is: I have measured some and the actual breakdown voltage is nc212 the BC and 75 volts for the BC Is there much difference and will it work in place of the BC? bc212

BC Datasheet, Equivalent, Cross Reference Search. Transistor Catalog

I am also bc212 just biting the bullet and go to ebay to get the exact ones so I know it will be right. First let me say bc212 I have never worked on this particular model, so anyone with personal knowledge is welcome to chip in bc212 intended here. The and were complementary. Being you have way more knowledge bc212 this I will trust your judgement.

The transistors in question are not actually necessary for bc212 operation it should work perfectly without them. Mar 16, Messages: On your drawing of the Studiot as soon as I can get to 10 posts I will PM you with the info.

Apr bc212, 18, 3, However I do want to learn the reasons why on the choice to further my understanding of how these components work.

But you need to determine pinout since they were produced in several configurations. Frequency rating and gain will also not be a critical issue in this application. Aug 15, 5. They form part bc212 the protection circuit so if you are bc212 you can remove them to get the bc212 parts working properly. I have an order with Mouser Electronics and this is the last item I need. That was foolish of me. Both transistors come in a variety of pinouts depending bc212 end letter so you need bc212 ensure a match.

Hello, Bc212 I have a zip-file with the data of a lot bc212 transistors: This is bc212 of the output circuit on a solid state guitar amp Marshall Valvestate that I messed up on. They bc212 turn on when there is sufficient current bc212 these resistors to provide base bias and drive. Bc212 obsolete items bc212 at a premium. They work by monitoring the output darlington emitter currents across the emitter resistors, R and R This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.

I’m replacing a BC transistor and of course they are obsolete.

Hello, Bc212 PM feature is not available for new members. Aug 16, Again I have plenty of the L variety. By continuing to use this site, you bcc212 consenting to our use of cookies. The BC has a current rating of mA and a frequency Bc212 of MHz, whereas the has a currrent rating of only mA and and Ft of MHz so you bc212 to bc212 the application here.
