Just one more...

THis one has a somewhat unusual design referred to as "parallel feed" in the output stage.

Essentially the same design as the previous amplifier, except for the output plate chokes and transformers.

This is actually an early (1930s) design which fell out of favor in the 1940s, but has come back again as it can deliver better performance.

More recycled / salvaged components.
