RCA Radio A B Battery VS019

Post by Michael Watterson » Wed Jan 30, 2013 7:58 pm

I wanted my B135 back out of the RCA 8BX6 radio into the big Pye PE94MBQ/LW

So I thought, why not do up the VS019, the RCA version of the B135 rather than another B135.

I used corrugated card with a 2nd layer at right angles in the bottom of the base and Cereal pack card for the top/lid part.

In real life it's red, not pink, I think the clear parcel tape film messes up the camera.

Anyone needs it, I'll upload the images to the library. It's not a scan, but drawn from studying a photo.

The ABSOLUTE maximum OUTER dimensions are 235 x 70 x 110 mm for the B135 / VS019 or it will not fit an RCA radio.

I found a photo but no scan of the RCA VS019, so I opened all the parts of my B135 and resaved them prefixed rca_vs019_ instead of everready_b135.

Next I picked up the photo's RCA red and made that my background and deleted all the existing content, except the connector.

A large size Kellogs Cornflakes lets you do top, front and bottom on one face with the two sides on the side. This is cover. The Base is same shape but smaller to fit in it and I used corrugated card with an extra piece in the bottom at right angles as the box needs to be strong if you fill with Alkaline (nearly twice weight).

The bottom part card cut to side with slots to allow tabs to fold which are stapled.

The battery holding part nearly done.

Next the lid, then the connector.

Three print outs, two are cut up. Layout on card to check

Then stick down

RCA Radio A B Battery VS019: Socket

Post by Michael Watterson » Thu Jan 31, 2013 1:09 am

The Socket

Press plug on a piece of paper with one hole already poked for "key" pin.

Some stuff you need
vs019_14.jpg



cut a PAIR of rectangles from marge tub lid (or old bank/credit/sky/phone cards)
mark outline of circle of case hole and then use paper as template to poke holes using a flat blade screw driver and twist.

Enlarge enough for plug to fit and use a craft knife to trim excess on reverse.

vs019_16.jpg

vs019_17.jpg

Make holes a little larger on lower sheet and colour top sheet "paxolin" colour if desired (I used a brown permanent marker)

Next make triangular profile socket inserts.


These work better than tubes and later Ever Ready battery sockets work like this.

Cut out and make "fingers" with scissors!

vs019_19.jpg


Coat all mating surfaces and inner box where socket goes with "impact" adhesive and allow to go "tacky".

Set bottom part on box and top cover guide / mask holes on lightly. Slide on cover carefully and use smalll screw driver to align to cut out and also top holes in "mask" plate to the bottom socket plate. NOW press together hard.

Next make up the battery holders...

RCA Radio A B Battery VS019: Wiring

Post by Michael Watterson » Thu Jan 31, 2013 1:36 am

Wiring the battery pack

vs019_23.jpg

The connections are all soldered with an extra wire soldered at the junction of 5th & 6th battery on 6 way D pack.

The AA are in 10 way packs. The rear is all taped with "Duck"/Duct tape to allow the units to fold in pairs to fit the cells. If you heat the connections too long they come loose.

One piece of thin foam under D pack. A small piece of dense foam with part thinned for behind socket is inserted and a larger piece along side.

vs019_22.jpg

Now check voltages are all correct polarity and placement.

WARNING: The 90V pack is dangerous shock risk and one of the jumper leads ought to have a 50mA or 100mA fuse. Take care inserting the cells.

vs019_24.jpg


Add a piece of thin foam or bubble wrap on top of the wires to stop the AA packs jiggling

vs019_25.jpg


Check the voltages AGAIN! A mistake could cost €60 in valves!

Fitted in the Radio.

The pack is covered in clear parcel tape to simulate cellophane wrapper and also to reduce wear on the tight "holder" as the case is to be refilled rather than disposable.

Don't fit fresh LT cells every time you go to use set. Only replace the LT (6 x D cell) when they are exhausted to minimise filament wear.

I got the Maplin Alkaline in "sale" in Limerick only slightly more expensive than "Budget" Zinc Carbon. The original was probably 6x D cells and a Layer pack good for slightly more than 125 hours. So the Alkaline should give about 250. The HT cells will be completely exhausted at about 54V (0.9V per cell) when the LT reaches close to 6V (1V per cell). "9V" Series filaments do work down to about 6V.
