Timing capacitor (C1) produces several times constants which is used to allow large voltage swings on the input due to the LM101's large input voltage range. The R2 should be reduced and the C1 should be increased to keep from exceeding these ratings. The smaller polarized capacitors is still used by returning them to positive supply voltage instead of ground, even though C1 requires the large values.
