Your name or email address: In particular they are higher gain, lower noise types. They form part of the protection circuit so if you are refurbishing you can remove them to get the main parts working properly.


Is there much difference and will it work in place of the BC? They only turn on when there is sufficient current through these resistors to provide base bias and drive. Have you identified the pinouts and where are you in the world?

That is what makes AAC special – The high level of cooperation between members. They work by monitoring the output darlington emitter currents across the emitter resistors, R and R So please check if the centre terminal of TR12 is connected to 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 How is the rest of the refurb going?


They will go in a small envelope. Pioneer Elite vsxtx water damage no power Started by Watin 34 minutes ago Replies: Given the age of the amp and the usage it has had I have decided to replace the transistors and diodes that were affected in this circuit.

Any comments would be appreciated and thanks in advance. The pinouts trabsistor the conventional way looking at the transistor from the dayasheet end ie up under it as it is mounted on the board.
