Firstly I would like to say hello to everyone for making this a great site that has so far been a really helpfull place. Thankyou.
I currently have quite a few BJT's that I originally intended to build a pair of mono-block amplifiers with. This didn't materialise as I don't feel confident enough to build this yet, I do not have an oscilloscope or frequency generator, yet!
There are :- 21 of 2N5401
20 of 2N5551
2 of TIP31C
2 of TIP47
3 of TIP142
3 of TIP147
5 of BD238
5 of BD237
5 of 2SA1667 (it says A1668 on the device though!)
2 of MJ2955
2 of 2N3055H
2 of MJ15003
2 of MJ15004
...and I think that is it ! phew.
What I was hoping to do was maybe to use the 2N5401/5551 for the headphone amp. In the past I think I read somewhere that BJT's could be parallelled to provide higher output powers.
I will be feeding the headphone amp from the pre-outputs on my amplifier, and I am using two different headphones : the Beyedynamic DT770pro (80ohms) and the AKG K416P (60ohms).
Maybe someone could give me some advice as to where to go from here. I am a qualified electrician and am aware of electrical principles but as I have said previously I am not too confident yet.
I would appeciate any help I can get.
Thanks
Gareth
