Scan? B135, Neda401, NC#753, RCA VS019

Post by Michael Watterson » Tue Oct 30, 2012 12:35 pm

Need a scan to make battery pack for the PE94MBQ/LW radio

It's 7.5/9V & 90V (only 9V & 90V used). Type W connector
I do have dimensions! :)
235 mm x 70 mm x 110 mm


First five listed on radio. Rest believed to be the same
  • Ever Ready B135
  • Eveready/National Carbon #753
  • Pertrix 85
  • Burgess F6A60 (or T6Z60 ?)
  • Rayovac AB994
  • Neda 401
  • RCA VS019
  • General 271 or 362

The LT will be 6 x F cells (Zinc Carbon) originally or 6 x Alkaline D cells will do as well to give over 200 hrs. HT would have been 60 layer cells maybe 1/2 size or a little less than PP9 "biscuits". Possibly similar to used in a B136

The 235 mm x 70 mm x 110 mm is one catalogue

But Pertrix 85 is listed as 240 x 70 x x 110mm in Radiomuseum.org

241mm just fits the battery location.

Using full width of 750 gm Kellog's cornflake packet, I can make outer front, sides, top and bottom.

The image is then printed in parts on 90gm paper.

The rear (with MADE IN BRITAIN ) is printed and stuck on an inner rear tray holding

6 x D cells = 9V in a single 3 x 2 layout holder
60 x AA cells = 90V in six off 5 x 2 (10 cell) holders wired in series.

LT is a little over 50mA, so Zinc Carbide a little less than 100 hrs and Alkaline a little over 200 hours for LT D cells. Zinc Carbon F cells, if you could fit 6 in, would be just about 150 hours.

If HT is about 7mA, then Zinc Carbide AA about 130hrs and Alkaline 300 hours.

LT is more critical than HT, so I'd be inclined to use 6 x Alkaline D for LT and cheap Zinc Carbon AA for HT. Cheap PP3 would be about 60 hours for €15 at best, The Cheap ZnC AA are about €9 for maybe 120+ hours.


I didn't find "scans" or layouts of any of the packs listed. My B135 is faked by editing and scaling a B136 (As I did for the B137)

Reading service info again on R&TS, it says LT is 68mA and HT is 13.8mA So.. I need to check stuff on the set and think about which batteries to put in pack

The Ersatz B135 on the Pye PE94MBQ/LW

A photo of a real Ever Ready would be nice (I have old Pertrix B&W, an RCA and an Eveready/National Carbon photo. A scan would be nice too. Can't find one for any version. I don't know if the "Battery Maker" made his from a real #753 or a photo and dimensions.

Anyhow, it works and looks the part. Connector as per my usual coffee tin and plastic sheet method.

Great work on the batteries Mike.

I don't think you get enough praise for the superb effort, innovation and quality you put into these replica's. I think the Batterymaker would agree you have certainly stepped up to the mark, and I for one appreciate the time and effort you put into this. The Technical Library battery section is testament to this too, keep up the superb work. :thumbl:

Regards
Chris

Fantastic work 8-) There is an Ever Ready valve portable that takes this size to but its an early one with a leather effect covering but can not remember the model now. I am also sure some American Zenith sets use this size to.

Mike, I can't imagine what Ever Ready uses that.
