[ARC5] Octal Crystals

[D C *Mac* Macdonald]

And the Johnson Viking Ranger also had an octal
socket for crystals mounted behind the front panel.
Either of two crystals could be selected by switch.
There was originally a "plug" to cover the hole,
but this is more often than not missing on these
rigs by now.

The first time I assumed someone had kludged the set (I think it was in a BC-221) but I recently acquired a very nice essentially unmodded BC-652-A that has a crystal for the calibrator plugged in the same way. Was this a normal approach, a "legal option" as an alternative to an octal holder crystal?
