One thing that I find odd is that the heater winding on the transformer is centre tapped. So, given that they could have used a 12 v bulb for an indicator why didn't they? Then the centre tap could be returned to ground to help cancel heater hum, after all, they fitted that him canceling output transformer?
Good point.

Well done! I'm sure your critique will have been very much better than the one Amie was hoping to find.
Actually, I reckon Amie's own critique will be pretty insightful, and with the benefit of an A316G actually present in the flesh
If the A316 project is being written as a school submission, may I suggest that it be sent to the BVWS too? I received my Bulletin yesterday, and editor Alex is appealing for articles. Seems like a match made in Heaven...

Another good point! And, to my mind, preferable. Though, it would need to be slightly higher voltage rating, for full HT voltage till PCL83 warms up. Whereas where it is, it would need only to be rated for the voltage drop across the load resistor (if Murphy were really watching pennies...)
