It took me awhile to find my Delta folder, because all that stuff 
moved when I retired. I'm still sorting it all out....

Nevertheless, I found that folder and I see that my memory was 
faulty. There is no line input LC in the 10B. The trigger circuit is 
different, so it's possible that this makes it more line noise  
immune. The circuit description says that some of the RCs in the SCR 
gate circuit are there to filter out false triggers.  

The 10B is more than a 10 with a switch. It's clear that they 
improved their circuit over time. In fact, I have schematics for at 
least 4 different versions of the Mark 10, and I think there must 
have been more, but all the 10B schematics I've found are the same.

For me, however, they have all worked well. I built my first Mark 10 
in 1966, and used it, in 2 different cars up until 1978, when I sold 
it with the car. Around 1974 I got my first 10B and then acquired 
several more over the years. Except for water damage and a single 
transistor failure, they've all served me well for nearly 50 years.
