Anyone have a schematic for the Yaesu FT101ZSD (10 watt version)??

I found mi schematic online with nothing more than a Google search for ft-101 schematic or circuit diagram.

A few different ft-101 model types appeared to be selected from.

is the service manual for the ft-101zd if that matches the zsd I don't know.

maybe someone else can advise the differences and if the info/schematics would be a match.

Yes, the ZD & ZSD are basically the same radio except the PA section is a single bottle in the ZD. So the PA section is different. I have the ZD Service Manual but don't know if they even printed a manual for the ZSD.

The real fear with the S model is that the power transformer’s primary is only wound for 100vac. There are a number of people stating that there are no other primary taps on the S version.?

That would make it actually a different PT with a different part number…. Etc.?

In my case I just got one a few weeks ago.

It has physical taps for 110 & 117 but, when measured/rung out, it seems they are not connected internally.

Thus, I'm using an auto transformer to get the 100 volts.

This is what I found in a Japanese 101ZD manual:

I uploaded a much better version in the files section!!
