This site features photographs and schematics of guitar amplifiers
built before the Second World War. This information is presented for
the guitar enthusiasts, tone freaks, solder junkies, and tube amp nutjobs who,
like me, are curious about the earliest days of musical instrument
amplification.
All of these schematics were drawn directly from amplifiers. Many are
not available on the web. Some of the amps were in original
condition. Some showed evidence of routine maintenance such as cap
jobs and power cord replacements. Some had been extensively
rewired.
The dating of these amplifiers is based on component date codes when
present. Otherwise, information was culled from the web. I welcome
any additional information, corrections, insights, and will try to update the
site as new information comes available. My e-mail: shane@prewaramps.com.
