I'm working on an early 400 that has the fuse style incandescent lamps. I bought blue and warm white fuse style LEDs. The light winding on the transformer is only 6.7 VAC with a line voltage at 120 and the 8 volt LEDs were dim. I considered adding a few turns to the light winding on the transformer to bump up the voltage. However there was not enough room in the window. I ended up with a voltage doubler circuit with a couple diodes and 2 x 220uf caps. I tried a few other options including using the +DC power supply with zeners and current limiting resistors but there was too much heat dissipation. The final circuit was hacked up on a recycled terminal strip out of the junk box.

So what's the opinion on the LED's? Warm white or cool blue?

Unless you're trying to match other components with Blue lighting, I prefer Warm White on most of my builds.
 
The warm white was my original intent. I also have a Marantz tuner to do and bought the blue ones for that. The person I’m doing this for also registered the same comment, warm white it is.
 
I put blue LEDs in my garage Optimus power amps. I think Marantz every time I look at them. A mistake.
Going to find some light greenish LEDs to match the original bulbs.

Warm White hands down.....
