[Amps] Drake L-7 amplifier power supply requirements

[A Lawrence Fibich]

I could use assistance from anyone who knows this Drake Amplifier and it's power supply. 1st I have advertized widely for an original one to buy - nothing.2ndly I did get a 'home built' power supply but at a road block as how to connect parts of it.  The HV section OK, and a secondary transformer provides a 120VAC to run through the on/off switch of the Amp to work the finals heaters circuit.  But I come to 'stop' in trying to know/figure out what more it needs into the circuits to the right of the finals on the schematic - like the interlock, ALC, meter, etc.  This homebuilt power supply does put out 5 VAC on the secondary but I don't know how to connect that to the Amp.Any assistance really appreciated.
