How good is your memory?
I see three close diode, the vertical ramp pump up diode that looks
like a regular black diode tied to the vertical vcc. I also see two
little glass diodes between the vertical ic heatsink and the flyback,
one is right next to the heatsink, one is a little farther away.

FWIW, here is a datasheet for the TDA8174:

There is an application circuit on page 3.
