Hi,
You ask some good questions. First of all, Somejoe posted a schematic from Electraprint, who "notoriously" (IMHO) runs tubes WAYYY too hot, and it may not be what you have at all.
This "hot rodding" of finals tubes has been prevalent for decades amongst the tube Manufacturers (to sell more tubes) and the tube amp manufacturers (who sell on specifications to end-users, "my amp is powerful").
It is "numbers"..... over quality .....or sonic beauty.
I find very few amp designers approach the tube amp from the basis of achieving long term reliability, and high performance COMBINED.
So, it becomes incumbent upon the thoughtful individual user, such as Somejoe - (who I don't know), to make changes so as to obtain long tube life AND high performance, and this can be done !!! Myself, and a few others, have talked about this up here.
You can plug whatever you want in there, 45-wise, and it will work, pass a signal. To determine for how long, and how good it will sound, you will have to measure the operating points, compute the dissipation (Ohm's Law), and refer to my original post, .... idealize it by using about 7 watts total plate dissipation.
Do NOT think for one millisecond that the amp "manufacturers" are infallible in their designs. Many experienced DIYers regularly out-do what many manufacturers offer. Cheers.
