A couple of other things to consider. In the R4C - if you upgrade to the Sherwood audio amp and product detector, you can unplug two tubes (less filament current). My rcvr also has the blue LED dial lamps which saves a bit more. I still run a small 12V fan that sits on top of the rcvr. a little air movement makes a LOT of difference.
