Cheap 100 to 150 Watt Amp

Jon Tirone

(Also known as John Fisher)

Here is a simple and cheap amp to make

I could have made the circuit board smaller but "what the heck"

 

Here is a suggested circuit for the power supply.

 

Please note:

I have been getting some e-mail's from people with problems to discover that there is a discrepancy with the pinouts on the BC558.

If you look up in the cross reference of the ECG or NTE semiconductor manual, you will notice that the BC558 substitute will differ in the pin configuration from the stock BC558. This goes for the BC549, BC549 and the majority of the BC transistors. So if you are using a BC558, please refer to my above drawing for the pinouts.
