Change suppliers. The ZTX parts are in the Mouser catalog. Farnell.com also carries ZTX but I didn't hit the website to see if they have that one. ZTX696 and ZTX796 are very high gain for a 140V part.
Out of my stock bin I would try MJE15030g and 31g but they don't have that much gain and you would have to twist the leads around.
