Given the numerous models of Seamaster being made by Omega SA even in the 1960s, the value for vintage models varies widely. For instance, a hand wound Seamaster 30 from 1962 in fair condition can fetch about $400 in today's market, while a 1969 Seamaster 861 chronograph can fetch over $3,500.

What decade is 1969?
It is in the decade of the 1960s. (Unlike centuries, which use the next higher hundreds value, the decades normally refer to the tens value of the year.)
What is the value of a rare 1960s foghorn leghorn bobble?
$500 plus depending on condition
What is the value of a 7-shot 22 caliber Rossi from the 1960s?
Depending on condition, 75-150 or so.
The average value of a single sine wave of AC is 42.5amps. what is rms value?
Average Current = 0.636 * (Peak Current)so Peak Current = (Average Current)/0.636RMSCurrent = 0.707 * (Peak Current)so Peak Current = (RMS Current)/0.707Because both equations are in terms of Peak Current, we can set them equal to each other.(Average Current)/0.636 = (RMS Current)/0.707(42.5)/0.636 = (RMS Current)/0.707thenRMS Current = (0.707)(42.5)/0.636 = 47.24 ampsAnother AnswerSince the average value of a single sine wave is zero, you cannot calculate its r.m.s. value!
How do you convert into maximum current if the average current is given?
Presumably you are referring to an a.c. current?If so, then the average value of an a.c. current is zero so, clearly, you cannot determine its maximum value.However, average current is more-usually applied over half a cycle, in which case, for a sinusoidal current, this value is 0.637 Imax. So the maximum current will be the average value, divided by 0.637.
