Three GE Transistor Radios
#12

These use class A audio...

I was looking at my Aqua radio again and noticed screws in chassis were loose, ummm someone's been tromping around in here... Lifted it out and behold, the small coupling electrolytics were new but ones in P/S and audio orig, ummm... So I replaced C16 and walla it sprang to life... Also replaced C15 which made a small improvement... It's still only drawing 13.5ma but is far improved, mebby I'll check the audio output bias resistors...

Not stated on A version but B with pin speaker says current reading taken at minimum volume... Current drops slightly at higher volume on both my A & E versions... The J is still sick... 

I dunno if it's available but a battery holder for six AAA batteries would probably fit in the A version... With smaller chassis and mini components, the J has room for the Goodyear blimp inside, a long holder for AA batteries arranged 2X3 would likely fit with ease...

BTW I tried operation on 6v, performance is all but nonexistent...
