I need to buy some transistor for repairing, which is not find in Hong Kong.

Be advised that you do not need to get the same part numbers.
For most purposes, replacing a small signal transistor with any other
small signal transistor (NPN with NPN, PNP with PNP) will be sufficent;
same goes for power transistors.
The exceptions are in the very high frequency applications or high
voltage applications.
With some care, one can even use a silicon transistor as a replacement
for a germanium transistor.

If you still have problems, then e-mail me at
with a wish list (quantity and part type) along with address.
I will then attempt to find them in my cross-reference books to find
recommended replacements; please try to keep the cost down.
