I confirmed with Ventex today and they do still manufacture the neon transformer for CV and SWEP1 which is available from their US distributors shown in the URL below.

I have seen postings over the past few months looking for this neon transformer and noticed that all of the pinball vendors are out of stock on this part (04-10947). The manufacturer model number is VT1510-12.
