Those 6.3V bulbs should work. You need 8 bulbs to replace all the original bulbs. Or, you could order a new LED Meter Light Board from White Oak Audio in "Warm White" to match the original incandescent bulb color. Then you will not have a heat problem inside your meters and never worry about burnt out bulbs again.
