I always get around that problem by substituting a combination of modern batteries. To get the 45 volts, just wire 5 nine volt transistor batteries in series. The 1.5 volt battery may still be available at a reasonable price.

I know that the one that I had (have?) is all tube.....there are no transistors in the radio, whatsoever.

If I ever DO find it, I think that I will wire some 9 wolts together and see what I come up with.

I have forgotten exactly how to wire batteries in series. Don't you wire the - of one battery to the + of another, and repeat for each batery, leaving the first and last terminals open to connect the radio, right?
