It is not possible to be more precise than this because individual tubes vary appreciably in their abihty to maintain a near-constant potential difference over a wide range of current. Cold-cathode-diode- stabilized power packs are therefore suitable for applications where the load is rather constant, such as precision oscillators, differential amplifiers, etc. 3-7kft ? 85V^ 7-5mA.
