I suspect that the damper diode is used as a time delay element (to delay B+ tirn on) and not for surge protection. Damper diodes such as the 6DE4 take a long long time to warm up - something greater than 20 seconds, if I recall correctly. Which brings up a point. If you need a damper diode for delay, why not get rid of the SS diodes and replace them all with damper diodes?
