250mW wideband FM amplifier for broadcast band

Components, pcb, schematic, board layout and parts list laid out.

The pcb: already printed, acid etched and drilled.

Removing coating.

Pcb ready for assembly.

Small components first (usually resistors).

I like to solder one leg of each device and check none came loose and are riding high before soldering other leg.

Stage 1 complete! Continue fitting components in ascending size order.

Sandwich loose fitting components between two boards before flipping to solder.

When all finished check for shorts, bridges and splashes in the solder.

And for my efforts hersm here's a wideband rf amp (for an oscillator stage) ready for testing.
