    Memo from the Astor Research Department and published on 9 April 1936, regarding the Astor Model 190, Ch AB and published in the HRSA Astor Book Vol.2, Page 114.

    The condenser C15, 0.001uF, +/-6% is too high. It is to be replaced by a 0.0008uF +10%. That is a condenser between the values of 0.0008 to 0.00088uF As mentioned in previous memo, C17 is to be replaced by a condenser in the bracket, 0.00025 to 0.000275uF. That is 0.00025 +10%. Investigation has shown that C2 & C9, 0.0025uF +/- 2½%, is in many cases 6% to 7% too low. These are to be dead true, or on the high side by 2½%. These condensers, when on the low side tend to create misalignment in sets. H J Collins
