Dear friends

I have a old radio with a unknown damaged transistor.
The transistor have the motorola logo and is write "8113 STASIS PNP" in the package TO-3.
I need change this transistor. Anyone known this motorola code and can identify this transistor ?

Thanks,

Aldovan

If it is a transistorized radio, then u may have same transistor in other stage(s). Check if the transistor is Ge or Si, then replace with any modern transistor of similar size and type(RF or AF). U will not damage anything. Install the pins properly.

Aldovan,

Are you testing properly this germanium transistors?

Junction voltages is about 0.1 to 0.2V, gain is low and lots of leakage is the norm...and not mean a defective component.
If you have only one TO-3, its a "A Class" output, steady state current was about 1 to 2 Amperes.

Hi m2003br,

It has nothing about Threshold amps...

Well, this is interesting

We were hoping Aldovan would then give us the make and model of the radio. Since this is still a mystery, no comment can be made by anyone. Agreed?

Now, either you have information that no one else in this thread has or you just jumped to a conclusion.

Would you care to share Marcos?

Hi Anatech,

Aldovan have another recent topic in diyAudio, where he asked for especifications for an old germanium TO-3 transistor, 2N176
and, all in all, old Motorola radios don't have anything with Threshold amps, and, from my best knowledge, all of this radios (existing in Brazil, at least) have germanium output transistors.

Hi.
If it is an old Motorola car radio with a single output transistor

any of the following can be substituted :-

OC35
OC28
2N176

Look on EBAY.

The 2N176 was the'original' car radio output transistor !!

See :- http://semiconductormuseum.com/PhotoGallery/PhotoGallery_Motorola_2N176.htm


Good luck

Andy


EDIT :- How many do you want ?
