Audio Transformer Replacement.
6/14/2003 7:34:09 AMJim Moore
I’m restoring a Sentinel model 35-B battery powered radio. The primary windings are open in the audio transformer and I could not make a repair. The Riders schematic (page 6-3) does not show the ohms. Where can I find the correct replacement for it? The Sentinel part number is 1331.
Thanks, Jim

Hi Jim

You need an audio interstage transformer driving a 19 tube. Use Stancor A53C or similar transformer. AES, tubesandmore.com , sells it as P-T156. Play Things Of Past, oldradioparts.com will also have a replacement. Their price is usually lower.
