2-3weeks and the local vendor that sells 2SC3320 is not that near to my place so i have to pay a little shipping charge which is 3$ next day delivery all in all it only costs 5-7$USD to ship the parts to you :D

Could you please check the price for shipping to Romania a small package at your local post office. If the price is reasonable maybe we can arrange for you to send me a couple of those transistors. thanks hmm, that sounds interesting.

Where are you from ? Hi Fred, NTE2311 seem really close to the original transistors, but unfortunately I cant find those either..

The characteristics do NOT have to be EXACT - I think your friend doesn't know his switching power supply circuits very well. I used common (off the shelf) NTE2311 transistors (with plenty of heat sink compound) and they work great! When using substitute transistors, ALWAYS meet or exceed the Voltage and Current handling capability FIRST. Speed may be a concern, but not usually. The bias is often easy enough to modify (Wow - Change a resistor, or add a diode). Hope that helps you! I’ve fixed several of those power supplies already with great success!

A friend told me that if I replace them with transistors that have some of the characteristics just slightly different the power source will break again in short time because the whole switching circuit was tuned in for those specific transistors.

I'm sure we could find something compatible. What country are you in and what retailers do you usually use? I’m sure we could find something compatible.
