Ich habe IMMER Respekt vor jemandem, der so viel Ahnung hat finde das super, sich überhaupt dazu zu äußern in einem Forum. Danke!
Also ich hab jetzt herausgefunden, daß der RM100 eine Boardspannung von 500V hat.
Zitat:
"The RM100 uses a plate voltage of 500.
We will use the plate dissipation for a standard 6L6 for this example which is 22 watts. Example: 22 watts divided by 500 plate volts equals .044 or 44 milliamps of plate current draw at idle. The 44mA should never be exceeded! Then multiply the .044 by .75 or 75% which equals .033 or 33mA. This is where your power tubes will be out of crossover distortion and will perform very well. There is an acceptable window of correct bias and if you want a warmer tone or what some players refer to as a "brown sound" you can use up to 90% of the maximum current formula which would be 40mA rounded off. Your tube life will be a little shorter at this setting but only by about 20%. However, I would NOT recommend this for Chinese tubes or tubes that are sold by the Big guys that have been remarked unless you know for sure what tubes they really are. The JJ Electronic 6L6 is a very stout tube and JJ claims that it will dissipate 30 watts. Since I like to run my gear pretty hot I will routinely bias them at 50mA in an amp that has 485 plate volts. The tone is very warm and the tubes stand up very well. I tortured a quad in my Fender twin for a year, set at 50mA at 480 plate volts and they were still going strong until I swapped them out for a quad of KT88’s but that’s another story...."

hmm... die reden da von mA. Die Angaben sind doch aber mV ?
