Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

RE: In what spirit do you ask the question ??..

I'll typically be at 47 mA and about 260 P-K, or 12.22 Watts dissipation

At this bias point how many hours do you think you can get out of this tube? I know it's a 40W tube and at this dissipation it is loafing, but I still wonder what that number might be especially as compared to a regular 15W 2A3 that is run under the same conditions.
