Do you have the correct pilot lamp installed?
Keep in mind that with most sets using that tube, the plate current flows through the dial lamp (and hopefully the resistor in parallel with the lamp) SO if the radio is pulling too much B+ the pilot lamp will blow.

Tube datasheet: http://tubedata.milbert.com/sheets/049/3/35Y4.pdf

It's about the same thing as a 35Z5, so this page from Chucks site might be of interest as well:
