Just be sure you connect the batteries to the right plugs. They appear similar on that schematic. 90V mistakenly connected to the tube filaments will fry the tubes instantly. I have a lot of battery sets using modern equivalent batteries that I build myself, as described. If you are unsure how to connect them, feel free to contact me by email and I can supply some pictures of how it is done. I can then post them on this thread for others, but I have so much stuff I need to know specifically what you need so you do not go into information overload.
