Looks like the attached file doesn't work.

Here is another one.


Edit:
I'm having a problem. I can open this attachment from the original file on my hard disk. However after uploading it I can't open the file. After downloading it Word tells me that I need to install some feature to enable it to open the file ! Any reason for this ?

It's time for me to turn in for the night. Since I'm not sure if you will have a problem with the .doc file from the earlier post, I'm attaching a copy as a text file using Notepad. Look at it full screen otherwise the lines could get mixed up.
Cheers.

I get it now,

those are extra 10V taps to add to the 100V primaries. That makes much more sense, and corresponds with their locations coming out of the transformer.

Thanks for your work on my behalf Ashok, I really appreciate it!

Now to construct an amplifier...

By the way,

I was able to open the first file immediately with word. It opened automatically.

Thanks!

always power up the unknown (and even the known ones) through a bulb tester.

I always attach each lead to a separate terminal of an insulated terminal strip. Makes voltage measurement easy and makes all testing safer.

I tried to open the doc file again using my second computer but it still says the file is corrupt. Wonder if it has anything to do with my ISP ? Many PDF files from this forum will not open either !

Yes Andrew , it's safer to test terminals when they are safely connected to a screw terminal. But often the urge to get it done quickly is so strong that.....
.............we do it the dirty way ! Invites blue smoke of course .....at times!
Now I am going to bed. Have a great day to all those who's day has just started and good night to the rest of you .
