[Milsurplus] BC-611 power

[B. Smith]

    I think for overall ease of operation and reliability a simple battery 
tray for the B plus and  a modern D cell for filaments is the way to  go. I 
purchase my 9 volt batteries at the Dollar Store.( two batteries for a buck) 
A tray of batteries will easily last a hamfest/rally season.  You can not 
service the Italian inverter, when they go bad they are done. Anyone can 
bend a piece of aluminum into a U shaped tray an fabricate  a wood piece for 
each end.

    I have built an inverter for a BC-611 but was never happy with the 
inherent noise but did successfully use it at Dayton on the 3885 net and at 
several hamfests and military rallies.

    Details of a simple battery tray can be found at the link below and at 
the end of that piece there is a link to the filament supply using a PVC 
holder.

    On my  filament page there is a CAUTION about using D cells in parallel 
as several of us have experience having a  D cell go bad internally and 
shorting out the other cell which created quite a bit of heat so  I do not 
recommend storing any set that has D cells in parallel.

    I now use a single D cell for the filaments with a PVC  spacer. Todays D 
cells are  much better than the D cells of WW II and a single cell should 
suffice.
