Hi, Gang

One of the eBay sellers has posted photos of the internals
of the Collins 51S-1 receiver. This is the general coverage
version of the Collins S/Line. The band switch
is especially interesting, sort of a turret arrangement
where the switched components, mounted on pc-board material,
revolve with the band switch.
