Some drilling and mounting work done this morning on the 4-65a SE amp breadboard:
Filament bias resistor array

Mounting pilars for the SSHV2 regulators
46 valve sockets

46 sockets, filament bias array and filament and HV supply connectors
During the afternoon, I managed to wire a filament supply for one channel 46 driver. Tested and working ok, now can move to the next one:
Filament regulator with its heat-sink at the back, anode loads and the 46 DHT drivers at the centre.
46 DHT driver under test. Gyrator anode load can be seen at the front
