Actually the ST70 stresses the heater cathode insulation in the 7199 and can prematurely cause failure. A simple voltage divider to raise the filament voltage to around +75vdc will increase the 7199 lifespan. Sound Practices had a nice little article on the subject several years ago.I can forward the article as a .PDF file if you'd like to see it.
