Hey everyone.
I've been kinda absent from here for a while. (busy with other things
)
But I am kicking around the idea of building this project.
Dave's Homemade Code Practice Oscillator
I know a simple practice oscillator begs the use if a 555 IC or even a couple transistors, but I want to make this one as kind of a novelty.
It looks like a simple circuit, but I have never built anything with tubes before (half the reason for wanting to do this in the first place).
I happen to have 4 random tubes on hand. None happen to be the #43 tube that is used in the circuit on the link above.
I do have a pentode, but it appears to be a 6L6GC "Beam Power Pentode"
6L6GC - **broken link removed**
and here is the data sheet for the #43 tube **broken link removed**
Is there any chance I can sub the 6L6 in this application? Or is that just not going to work? I see the heater voltage and current are much different, but past that I just don't know enough about tubes to decide if i can make it work or if I should order a different tube.
Any help would be great![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
