Been digging through info for about 6 months now.
Next project, HF all band amplifier.
Took me a while to decide on what tube to use. So going to use the 811a since a have a shelf full of them. Now to decide on how many to use. Seems 4 was the magic number but maybe more. Have to do the math.
I got this huge black ugly case I need to do something with.
Pics to follow as this comes along.
May be requesting folks to check their junk boxes!
Below is the chassis I am going to use. For the last 20 years it has been a power supply ranging from 5 to 800 volts. Time to give it a new face and use it for something more usful. It this case, an HF Amplifier.
It is a rather large enough chassis to handle the project.
You can tell by the size of the watt meter how big the case is
