Ron,the Eveready 415 for the B supply is still available, but the 4V Eveready E233 for the A supply is not available. Have you thought of making an adapter for it? The battery is 1" diameter by 2" long(same diameter as a C size battery, but 1/8" longer), with the positive terminal on the flat end. I soldered 3 AAA's in series with brass shim stock taped to the ends. There's just enogh room to slip them into the battery compartment, and even though the AAA's are only 1-3/4" long, the spring terminal is long enough to keep them contact.

The original Eveready E233 lasted about 50 hours and the Eveready 415 about 100 hours. I'm guessing that the AAA batt pack I made will last about 6-8 hours. I have about an hour and a half on them so far. Bob McGarrah has a lot of information about specifications for the 838 and other transistor radios with many excellent pictures:

i bet if you use alkaline aaa's they will run longer than the old zinc/carbon you are replacing.

I don't think so. I've got about 8 hours on 3 AAA's. I got far less than that on AAA rechargeables. The original battery lasted up to 50 hours.

Hi, Ron and DA:
i have a question. I own an Emerson Transistor II radio, but the A battery polarity mark is gone, so could you tell me whether its + polarity should be connected to the spring on the chassis or the little compartment lid? Thanks! ----Dan

The positive terminal connects to the lid. This picture shows what I used for a battery substitute.
The brass shim stock is placed on the positive terminal of the battery and then the lid is slid in place. The shim stock insures good contact
