PNP Audio Output Transistors Silvertone Console

rhaines7 · 2nd June 2011, 01:44 AM

Just acquired a Silvertone Console with early transistors, I have the schematics and need to identify the output transistors for replacement, very low output. Any way to identify these transistors, the Sears part numbers on the case do not cross reference. TO3 cases, maybe Germanium? Any help would be appreciated. Thanks

If they are PNP germanium, then OC28 or equivalent are probably as good as you will get.

Are you sure they are TO3 cases, not the smaller version?

Thanks Andy,
I think you got it! Plus, I finally got the cover off and they are smaller versions of TO3. I'll keep you posted on my progress. Thanks again.

I thought they may be.

You want AD162 or equivalent -- quite cheap !!
