Hmmm... There is a difference at C17:

[Image: https://lh3.googleusercontent.com/-5no5F...520C17.JPG]

I have two 200uF in parallel instead of one. It looks original, so I assume it was intentional. It seems like this would just slow down the beacon response time... maybe? My serial is 15732B, so I was using the first manual. The later service manual still shows 200uF for C17, so it doesn't seem like a change on the way to a later version.

Maybe this unit had a unique "Service Procedure"? Oh well.

Any suggestions on the dial lamp voltage? Although the beacon is 12V, I can't find anything about the transformer, nor a Service Procedure that says what it should be. If nobody knows, should I just fire it up after recapping and measure, then guess what should go in series with a 56ohm resistor (R72)?

Thanks,
Devin
