About this model
In 1956 Unitronics Corporation bought both David Bogen & Company and the Presto Recording Corporation, a maker of recording discs, turntables and amplifiers, and combined them as the Bogen-Presto division in Paramus, New Jersey. The Presto name was dropped after 1962. This DB-230 is an integrated stereo preamp-amplifier, which the listing dates to 1959 and rates at 30 watts per channel. Its phono section had a turnover selector for RIAA and 78 rpm equalisation, a useful feature on an amplifier built just as stereo LPs arrived and 78s had not yet disappeared.
The seller described it as recently serviced, with cleaned controls.
