Default Bored...2n3055e amp?

Hey I'm a little bored and got two of these lieing around, a couple of 4558's and 741's too. Would like to know if theres a simple amp I could build out of them.


Doesn't need to be powerful, a watt or more would be nice :-p

Have a look at Rod Elliott's site.
You will find many simple projects to make good use of these parts.

alright, well I was hoping for something that ony used one transistor and an opamp, I could use a voltage regulator for bias. Any curcuits that could use this?

If you have two 2n3055's then you could build something with a quasi-complementary output. You would need two medium power transistors such as MJE340/350 as drivers though.

These parts are obsolete and it may turn out to be waste of time to build up something from these. For also very low price you will get tl07x or NE5532 op-amps, which are way better. Modern power trasistors will be probably something like 2$.
No need to use your old dirt whereas silicon costs nothing nowadays, main expense is transformer, heatsink and PCB.

Try something original. What about this one, dating from 1973 and due to P.L. Taylor ?

Is this more what you are looking for? You could replace the darlingtons with what you have for transistors. It won't produce much power, but you said you wern't looking for much in the first place.

nice, I think that will work. If I set it up in multisim and test it will it give me close to accurate results? By the way... multisim looks very close to p-spice.. I downlaoded p-spice one time but I couldn't get it to work.

what voltage do the diodes need to be ( or are they not zeners?)
