I have seen a lot of replacement P2 non lettered crystals for sale, NOS condition. What I am wondering, did Pulsar ever stock any P1 replacement crystals ? I have never seen one for sale. Has anyone ever heard a story where someone had to send a P1 back to the factory for a new crystal ? I can only imagine if a NOS crystal came up for sale how much it would fetch. I wonder if Pulsar even kept a few spares on hand ?
