Heyraz, yes, I absolutely decorate my Christmas tree with vacuum tubes. My wife thinks it's ridiculous, but I think it looks very cool. I used to know how to post a picture here, but have forgotten.
I did the same thing back then when I replaced the incandescent light bulbs in my house with CFLs. I was in a really cool store that was selling incandescent bulbs that were painted in things like snowflake motifs and stuff like that, and I stole the idea from them. I figured vacuum tubes would also serve the bill.
None of the tubes (or lightbulbs) are connected, electrically. They just serve as ornaments. I probably will one day when I have enough on the tree to make a meaningful statement. It would be just the heater filaments, so they light up. But, if they were biased, you can bet it would be Class A all the way.
Oh, one other thing to look at Devilboy is to make sure resistance in the bleeder circuit of the power supply circuit is high enough. If it's not, too much power will be present, and you'll be arcing over rectifiers with no trouble at all.
Speaking from personal experience and expanding upon what Ralph intimated, the Chinese are great at screwing up both the design and implementation of high-end audio products. I'm not sure how old your amplifier is, or how long you've used it without encountering this issue, but what I'm saying is don't assume they specified/figured out the right value of the resistor here or even if they did, that the right value was installed in your amp. Their piece to piece variability can often be breathtaking, sometimes making their own schematics look like downright works of fiction.
Continued luck in solving this problem!
