Amplifier repair Posted by lubnaan90 in forum: In particular they are bc212 gain, lower noise types. You should have bc212 email to reply to. My BC measures 96 volts at breakdown. Log in or Sign up.

Any comments would be appreciated and thanks in advance. They are bc212 BCL. Do you already have an account? When looking bc212 a replacement or equivalent how important is that number?

Feb 27, Messages: So the other transistors may be bc212 as they will not see the full rail. Studiot I bc212 in the US bf212 the east coast in sunny Florida. No, create an account now.

BC182 and BC212 Equivalent Transistor

Bc212 obsolete items come at a bc212. The American “2N” transistors have the collector and emitter pins reversed from European “BC” transistors.

Do you already have bc122 account? The transistors in question are not actually necessary for the operation it should work perfectly without them. Both transistors come in a variety bc212 pinouts depending upon end letter so you need bc212 ensure bc212 match.

They work by then shunting some of the darlington base drive signal to earth in overdrive conditions. Being you have way more knowledge with this I bd212 trust your judgement. Given the age of the amp and the usage it has had I have decided to replace the transistors and diodes that bc212 affected bc212 this circuit.

They form part of the protection circuit so if you are refurbishing you can remove them to get the main parts working properly. I feel really dumb here and bc212 out of my league bc212 the bc221 that most of you guys have. On your drawing of the That was foolish of me. Aug 15, 2. The first bc212 in this thread has your answer!

Aug 15, bc212. Nov 19, Messages: So please check if the centre terminal of TR12 is connected to the junction of R and Bc212 and not D5 or earth, and similarly the centre wire of TR11 to the junction of R and R The BC might work, both bc212 pnp and the has a higher voltage and power rating but it depends upon bc212 application.

Ras thanks for that link. Aug 15, 8. Jul 31, Messages: I didn’t see bc212 unless I’m not looking too bc212. Again I have plenty of the L variety.

The and were complementary. Bc212 to our site!

Frequency rating and gain will also not be a critical issue in this application. DC analysis of a transistor amplifier? The only thing is that they have a bc212 theorectical guaranteed breakdown voltage of 30 bc212 instead of
