Hello Group, Working on a SB1000 at the moment. Looking for a replacement 100-1608 vernier drive and (4) 230-6818 meter lamps.Thought maybe Ameritron ( MFJ AL80A) for the drive and lamps but don't see their listing for small parts. Outsourcing the drive looks promising but no idea of the specs for the lamps. Thanks. Bruce WK3A
