Fri 16 Jan 1942: snow and gramophone

.
Raw cold, bitter wind, dull; the snow has thawed slightly but freezing again later. Did all the shopping locally in the morning. Altered the gram.so that only two stages of amplification follow the pick-up instead of three; the latter is too powerful owing to the great output of the Marconi pick-up. Tested it and found in order but accumulator running out, so not a fair test of quality which should be superlative.
