Yes, I got the manual there too. I believe that distilled water cleans up a leakage mess. But I need to REPLACE the batteries in my 403b (NiCad, 6.5v, 225 mAh...
I am only able to find NiCad s as 1.2v singles, or multiples thereof in "packs", so....6.0v or 7.2v....with much higher mAh than spec'd in the 403b's schemo. ...
Longer mAH will simply run longer. Use 7.2 volts and put a 1N400x in series with the pack where it feeds the circuits. The charger goes direct to the pack. ...
Thanks peter. I guess I could use a 6.0v pack (in series with) 7.2v pack = 13.2v (per rail). So the zeners' polarity after batteries would look like this: ...
