Hello again dear Radio Collectors.  I managed to get a new B battery for my BP-10 from Antique Electronics Supply.  Now I need to know how to remove the chassis from the case.  It's not at all obvious how this must come out.  If anyone can give me a hint, I would most appreciate it.  Thanks / danke sehr!

Okay, I'm going by memory on this, so pls bear with me:

First thing that needs to be removed is the main body of the receiver.  There are three screws to remove--one near the tuning cap, one by the volume control and the last near the speaker and A battery holder.  You may have to undo the A battery holder to reach this last screw.  Once those are undone, the middle jacket can be lifted off. 

The antenna straps will need to be unsoldered from their leads.  You can then remove the four nuts that fasten the chassis to the chrome fascia panel.  Lift the chassis up from the speaker side, slide it enough away so that the thumbweels clear the panel and lift away.

Thanks 

Hi Bill, thanks for the information.  You were exactly correct.  All I needed to do was remove the three screws and the case sleeve came right off.  I cleaned off the corrosion caused long ago by leaky batteries (the old B battery had a 1948 date stamp on it!)  I cleaned the tube pins and the glass envelopes.  All four tubes appear to be original RCA's.  Note to anyone else with these - the ink on the tubes is very fragile and will come off even with gentle rubbing.  I only cleaned the parts without writing.

Then just for the heck of it, I connected new batteries and turned it on.  And it worked!  It sounds great, even with almost 70 year old paper capacitors still in it.
