You might remember Michael Saunby, he was the guy that had the interesting clock that we were trying to determine heritage for. The clock was almost featured on Antiques Roadshow but unfortunately was left on the cutting room floor. Michael works with lots of antique electronics and this 1930 vintage amplifier and speaker is a great example of what can be done with a mix of old and new.

"The original amplifier was typical for a 1930s broadcast receiver, a single ended pentode with tone correction. The valve chosen was a high slope pentode type AC/SP3; as used by the BBC in pre-amplifiers from late 1930s through to the 1950s."
