[Boatanchors] Need a TR1119 solid state 12AU7 For Heath VTVM

[Mr Bill Mellema]

Guys,
The Solid State 12AUF went south in my Heathkit IM28 VTVM..The TR1119 was part of a solid state upgrade kit (included a 6AL5 solid state replacement). 

Does anyone know where I can buy one a replacement? 

Thanks,
Bill N3WM
