Ok, this is about the amp in this thread, but on a totally different vein.

I just did the dim bulb test and everything went off without a hitch. Then I setup the bias and ran into a little curiosity...
One would max out at 53v across the cathode resistor and the other would bottom out at 54v across the other cathode resistor... Oh, wait. I just realized I installed 10k resistors instead of 10ohm. Ok, I'll fix that soon.
Anyway, I tried it out and it sounds GREAT, but has absolutely no volume. Also, the power light doesn't come on, which is in parallel before the tube heaters. I replaced the bulb and still no lighty light.
So I am in need of help. Does anyone have any ideas of what could be going on. Major issue is the volume. If the 10ohm resistor will fix that, cool. the power light isn't a major worry unless it sparks something in your minds that could be a major issue.
Also, I just realized I need to drain the caps. 4.5k 15w resistor? will that be fine?
