[Milsurplus] FS: 15 Volt Battery Adaptor for Simpson 260-5P and AFP-1

Group,

Simpson Model 45002 adaptor to replace #415 15 Volt battery in Simpson 260 
Series 5P and Series AFP-1, $15.00 plus shipping.  Includes new Eveready #411 
battery (worth $10-$12).  This is approximately my cost per adaptor and battery. 
 No profit involved.  See below for why I bought them.

Some months ago, having two of the AFP-1's, I was looking for a source for 
the 415 battery, but it was discontinued.  I then discovered that Simpson had 
made an adaptor to use the readily available 411.  But even to a distributor, 
Simpson had a 12-piece minimum.  So I looked into building two of them (which 
recently turned into three of them required).  Figuring machining time, it 
looked like most of a day when it was all said and done, plus cost of materials.  
Then I discovered that the adaptor unit cost included a new battery, which 
meant that the adaptor itself was less than $5.00, and the thought of wasting a 
day to save $15 didn't sit well.  Finally, I blew another fuse in my main bench 
Simpson 260-5 (for those who don't know, the fuses are soldered to the circuit 
board) which was why I was trying to get the AFP-1's running in the first 
place (they do not blow fuses when you forget that the meter is on Ohms and stick 
the probes across a voltage source).  So I called Allied back and told them 
to place the order.

Since I'm rambling waiting for the dinner bell, and because someone is almost 
certain to say I should have just converted them to use a 9-volt battery, 
here's why I didn't.  First, it won't fit (too long) and I declined to bust up 
the bakelite so that it would.  Second, the conversion cost per meter (time and 
materials) definitely exceeded the $5.00 per meter savings.  Third, I'm not 
sure it would have worked anyway, given that a relay is involved.  Fourth, at a 
minimum the amplifier would have had to be redesigned, and I pretty much quit 
playing with anything lacking a filament voltage spec when I lost my last 
Corporate Karate fight in 1999.  Fifth and final, when I bought the first two 
meters from Fair Radio years ago, they had a bunch of them.  And I figured some 
might still be floating around with list members who are in the same boat I was 
in.
