Hi Mark
<So the autodyne is the oscillator/mixer of the day that wasn't able to include a pentagrid, because it wasn't available yet?
Yes.
<So how does the oscillator/mixer work using the 36 tube? How is the design different from one using a pentagrid?
Well if you look at the diagram the input is on the control grid and it oscillace between the plate and cathode. The output is take off of the bottom of the osc coil.
<How is the design different from one using a pentagrid?
Alot more grids to use.
<What do you think about following the available tech tip to replace the 36 with a 77 tube?
Would most likily would give you a bit more gain as it is a little newer. Check the mu ratings.
