Here's a great way to test the meter on a Trip 35.Set the exposure dial to A,cock the shutter,cover the lens and press the shutter release button.If the shutter fires the meter is toast.
I tweaked my Trip to fire at 1/200 without a working meter.Darned if I can find the article.Maybe someone else has it.Very easy steps to follow.Default shutter speed on a Trip is 1/40.Almost useless.
