If I read this correctly a phono graph and radio and above an electic fireplace???
Can't be...??? Suppose if the fire were on the tubes should warm up pretty quick, ...let's see ... caps could dry out pretty quick too, ...Ha ...it maybe even warp a few records on the platter!
...in a bizarre sort of way this could be an early engineering example of 'toast' for tube radios. Of course, the modern version of 'toast', as I've learned from my son, is a software program that exercises a CPU, generally causing thermal distress to the processor, all the while the limits of processor speed are determined!
