CHECK these [mportant Points when you consider RESISTORS (1) Accuracy: Resistance value within 10% tolerance; the accepted commercial limits- Ohiohms are guaranteed to be within this range: (2) Permanency : Resistance value unchanged by age: The resistance of Ohiohms remains un- changed over an unusually long period of time; whether in use or in stock: (3) Absence Of Noise: Quiet regardless of positior ALL SIZES IN STOCK in circuit: Many static noises are due to FROM 500 OHMS TO faulty resistorga Ohiohms are noiseless al- 2 MEG. waysa 1/3 eache (4) Low Heat Coefficie ata Resistance value un- affected despite heating up in servicea Ohiohms have an extremely low heat cos efficient: (5) Freedom from Capacity Effect: Resistors Send For Free Catalogue To Owr Nearest 4 ddres8a should not build uP capacity (similar in mmanner to a condenser) as this often throws the set out of balance: Ohiohms are coms pletely free from capacity effect: (6) Unaffected by Humidity : In some sections of the country humidity has the effect of altering INTERNATIONAL RADIO CO: LTD-, resistance values in resistors. Ohiohms with; 254 Castlereagh Sts; Sydneys NS Ws, Australia, stand humidity effects admirably well. (7) Low Voltage Coefficient : Fluctuations in volt? age may vary the resistance of some resistorsa; CHAS. E FORREST, Managing Directora Ohiohms, however; have such a low voltage coefficient that the change is practically negligible: INTERNATIONAL RADIO CO: LTD,, 403 Bourke (8) Mechanical Strength: The ability to withstand Street; Melbourne: Victoria, Australiaa rough handling: Excessive vibration, drop- ping resistors or abuse in transit result in some resistors being damaged to the point INTERNATIONAL RADIO CO_ LTD , Brunswick where they are unfit for service; Some still Buildings, Queen St , Auckland, New Zealanda weaker resistors disintegrate simply with age:' Ohiohms can be dropped on the floor or similarly abused without effect: MILES NELSON (Special NZ: Representative) (9) Appearance: While beauty with resistors; like Brunswick Buildings, Queen Sts, Auckland, NZa humans, is only skin deep; nevertheless such factors as straight wire-leads, paint-finish de- void of pores; and other points of appearance are also important from a service and dura- bility viewpoint: Ohiohms challenge com; MiL SIZES IN STOCK FROM IN 1 WATT GAPACITY . parison for good appearance: FROM 500 OHMS TO 2 MEGOHMS: (10) Color Coded: Painted according to RMAv 1/3 each standards:' 0 BI H � EI MI RADIO OHIOHM BR ESISTER $ All Ohiohm Resistors are Stamped Ohiohm
