Was wondering if any of you had detailed pictures of the AL-811

With all the parts I have laying around I am going to attempt to build one for a learning project.
I have all the manuals and schematics plus a few pictures that do not show much detail.

Be nice to see how the parts are laid out.

Thanks

You can also reference the Collins 30L-1, but the tubes are laid out horizontally in that amp. In the Ameritron, they're vertical. I have some old Handbooks which contain amplifier projects that are based on the 811A.

A word of caution about using Svetlana 811s in a horizontal configuration: Occasionally, their filaments will sag enough to short to the grids...
