So using the old water pipe analogy, wouldn't you reduce
the resistance to open up the flow? I have read that 6L6's
Should be around 250 Ohms. Platefire

Yes. If you are talking about a pair of push/pull 6L6s. But for a single 6L6 you need twice that amount, 500Ω. 470Ω is close enough.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!
