I haven't built it but that looks right according to the text on the PCB. If you want to do a double check, you can check L1 at the + of the RCA to the middle white wire after the switch (I assume input to the linestage) with an ohm meter. Then flip the switch and see if the reading changes. Should be closed or open. Then do the same on the other side.
Nice and tidy build BTW! That is a nice PCB.
If you haven't seen it, Mark Johnson has a nice SMPS filter which I believe is available in the DIYaudioStore. Good for cleaning up the power a bit.

Thank you, although still have a lot to learn about electronics. I feel that my soldering skills are getting better. I have a separate power supply Q11 that's in the same size chassis. Might be a little overkill but I can use the power supply for my new tube korg also. I may also squeeze in a filter in the same chassis...got plenty of room.
Soldering looks good to me. I use either Cardas Eutectic solder or the DIYstore FireBall Solder with great results. Also a good soldering station makes all the difference. I hear Kester works good but I haven't tried it. The Hakko FX888 is a great soldering station. But whatever you are doing seems working just fine.
Nothing wrong with giving the B1 a good meal. Shoot some pics when you get it wrapped up.
The Korg Nutube is a great preamp. I noticed on mine that the linear power supply plus a few other mods made it a little more dynamic and smoother sounding. I have film caps in the signal path and larger electrolytes for the power supply caps. I also put a nice stepped attenuator on it. I suggest building it stock and trying a couple of upgrades here and there.
There are a couple of people in the B1 Korg thread who posted the specifics in regards to film cap size and some of the other mods that I mentioned.
