Repairing the Audio Oscillator section in my B&K Mod. 970 Radio Analyst, which has a bad 16L64 NPN transistor. I'm not able to find a replacement.
Any help is more than appreciated.
Note: Revised and corrected. The Transistor number is 16L64 NOT 16L46 and it is a NPN NOT a PNP. I'd like to apologize to every one for my mistake.
I found the schematic and will using the instrument for repair.
Answer
Using NTE's cross reference, 16L64 can be replaced by NTE107 which is described as a "Silicon NPN Transistor - UHF Oscillator for Tuner" and comes in a TO-92 package. As the exact copyright status of NTE literature is unknown to me and to avoid any copyright issue, I will not be posting the specifications here. Instead, here is the link to the datasheet.
If you are in the US, you can check for availability of the NTE part using the "Check Stock" button. I highly recommend buying from NTE to support their business. They had been providing good cross reference service for decades (formerly known as ECG by Philips).
Other common transistors for replacement are 2N3855A and BC549. A preferable replacement from Fairchild is KSC388.
