Can I substitute a standard 9 volt battery? The older style is hard to find and expensive. This was in a old Toshiba sw/mw transistor radio I came across. I would like to test it to see if it works, without damaging it.
Nine volts dc is 9 Vdc, no matter the source. Smaller batteries generally have shorter useful lifetimes, of course. See:http://www.antiqueradios.com/forums/viewtopic.php?t=146840
Scroll down -- it's just the info you need!
I took a look online and there is a reproduction battery only 220 mah and costs $20.00
If you look up an energizer 522 it's 600 mah and only costs $4.00
didn't look at dimensions but if it would fit...........
