Need help with connecting OPT.

[juoto]

Hello

First of all, sorry for my bad English.

So I´m building an amp with this schematic
http://www.bonavolta.ch/hobby/en/audio/kt88_1.htm

and I have a question about connecting Hammond 1627SE OPT to that amp.

Blue/yellow goes to pin 4, that I know...

But shoul I put Red or Blue wire to pin 3?
I´m building my first amp...

Thanks a lot!

Schematic & Hook Up Data:
SE Schematic

Notes:

- RED wire connects to B+
- BLUE/YELLOW wire connects to screen (optional use)
- BLUE wire connects to the tube plate
- The 1642SE & 1638SEA do not include a primary screen tap (as they are designed for triode applications).

Look up tube pin layout for your tube>
