The rough-in front panel. The meters placed are for grid and plate
current. Another (3rd) meter will go where sketched for RF Volts.
The two holes beneath the Plate meter are for ALC and RF Sens adjustment. One hole is filled with the 100k ohm ALC adjustment. The other hole on the left of that will have the 25k ohm RF Voltage Sense adjustment.
The top light for Filament, and bottom for HV Cont.
The two SPST switches will go beneath the RF Volt meter. Another set of controls will go under the ALC adjustment as needed (for fine tuning or other functions)
The Tune and Load air-variable caps will be adjusted by the two holes on the left vertically aligned. No knobs shown because I need to put an extender on the shaft to bring it through the front panel.
The front panel is 1/8" aluminum cut 18" x 12". It is revision A. Just a mock up panel. The next revision will be cut approximately the same, but taller to stand the amp higher. There is some circuitry under the RF Tank that needs more room than I originally thought.
The bandswitch is mounted in such a way as shown that the 10m band is about 2-oclock position and 160m is about 8 oclock position. That will change. I will remount the bandswitch so to make the 160 thru 10m spread more even so that 160 will appear about 9 o'clock and 10m about 3 o'clock.
There is nothing below the bandswitch because in the RF Tank, a big coil is sitting there!
The input circuit wiring will come into the cavity between the RF Tank and front panel from the right side post. The meter, ALC, bias, and PTT circuit will be installed above and below the chassis to the right of the RF Tank.
I am debating about how to back-light the meters and how to provide illumination for the bandswitch selection and tune/load dial. I might use a peice of plexiglass that is etched in certain patterns/letters/numbers on the surface to diffuse the light and create illuminated markings on the front panel.
