:!:

Some things you DON'T forget !  L:

Like your first Model Railroad power-pack ... & other firsts I'll save for my memoirs !!  ;)



It was stashed away for years in Ma & Pas loft ... As 'progress' dictates for some things.  :P

I actually had a couple of even older throttles before this ...

... one of them even had a TRANSISTOR ! in it ... Well I never !  :shocked:

But back in the day, I was inspired by this lil' ol' power-pack, which Pa bought 2nd hand for me as a kid !  :)



It had 'momentum' for one ! ... NICE !  :bg:

Now you DIDN'T get THAT on old 'Tri-ang' or 'H&M' throttles back in those days.  :old dude:

Anyways without further ado ...





A 'Codar Controls' ... Model ... something something something.  ???



When I stumbled upon the pic. on the Net, I did try to find a better one than this, but no luck.  :f:



I gave her away some years back, to a friend who thought he might use her for his kids starter layout.

Probably now rusting in the back of his workshop somewhere !  :time:



Oh well my D.I.Y. home built 'momentum' throttle is much better than ^^ that ol' dawg anyways !  :cool:

But memories are memories !



L  a  t  e  r  .  .  .



:pimp:

Hi analog fans !  :wave:



I never had the manual for my 'Codar Controls' power-pack back in the day ...  :f:

... oh well ...

... you just plug it in the wall socket & connect 2 wires to the track & THAT'S IT !





Forget about all those rocket-appliance DCC programming complexities ...  :brill:

... & all the tons of wiring involved in those battery powered R.C. transmitter conversions !  :f:



With INERTIA ! as well !! ...  T :cool: :cool:  C :cool: :cool: L    :slow:



The 2 little push-buttons at the bottom right, were for a steam whistle & diesel horn ...

... you didn't even have to rewire your locos either.  :shocked:



:pimp:



Si.

I can't 'resist'  :doh:  (groan)  a good ol' fashioned analogue controller ...  :old dude:

... & of course D.I.Y. ones, are just simply the best of all !  L:



I was MEGA impressed with Charlies basement boxes of Bakelite(TM) ...  :bow:

... so thought I simply HAD to Post some of his pix. here.  :bg:


:java: :brill: :dt:

Sure do and still use them.

The only disadvantage can be the ageing selenium rectifier.



BTW, I remember the first-ever transistor throttle I built,
from an article in IIRC 'Railway Modeller' in the early sixties.

All Germanium, pure regulated (!) DC.

Yes, it had a feedback transistor to stabilize the output voltage.

That made the semiconductor count of this circuit  three,
relatively expensive those days.

:shocked:  HOLY COW !

You must have been a Millionaire Helmut ...  :cb:

@Si

In the 50's and 60's, there was a guy called Linn H. Westcott AKA 'MR editor',  :old dude:

who published a lot about electric and the then newfangled transistor circuits.


He designed the so-called True-Action-Throttles.


They were refined by Blunt and Burgess.
