Gentlemen: 

I have a 25-year-old MRC Tech 3 "Power Command" analog controller with Voltmeter, Ammeter, Rotary Speed Control, Direction, Brake, and Momentum switches, and fixed voltages for turnouts, trackside lighting, etc.

I used this controller many years ago for my big LGB train on a 150-foot dogbone layout running between my house and garage.  It did the job with no strain!

After laboriously wading through the over-abundance of functions on my new MRC Prodigy 2 Advanced DCC controller, it was a breath of fresh air and a pleasure to go back to Analog control, even though my new Atlas O-Scale 2-Rail GP60 loco has full DCC and 16-bit sound on board.

I'm still able to get the sounds I want by manipulating the Direction switch with the required manual "touch".

Is this a testimony praising the Analog over the DCC control system?

Could be....

HAL

Don't know if it is praising analog over DCC but it does speak well of MRC how many 20, 30, 40, year old power packs I have seen which are still going strong.

I have an MRC Tech II pack that I still use from time to time. It still works like it was new but then its never really seen any heavy use.

I like those old heavy, one-piece MRC analog packs!

They have that big man-sized rheostat speed control knob that feels like you're really in control, instead of that wimpy little "fingertip" speed control and a dozen buttons that have no functional names.

I put my new 3-piece Prodigy II Advanced DCC back in its box, in case I need a backup sometime.

Cheers,

HOWL  (hal)

Sounds like Hal discovered 'Plug & Play'...

It doesn't have ... "that big man-sized rheostat speed control knob" ... which Hal liked ...

... But the Tri-ang P-42 'Circuit Control Unit' is a ROCKIN' lil' resistor !!  :pimp:

I'm not sure this is what HOLSTERHAL was on about ?

Is this an old MRC 5-Amp with meters & big controls ?

Oh, I bet HostlerHal was a loco-slinger, not a gun-slinger:cb:. You don't need a holster for that.

Well - this one I got 1960 and it is still going strong. Selenium rectifier and paper-foil capacitors ( the ones that effectively short-circuit everything when failing, which they did rather often ) for suppression in the mains input.

Hi Helmut :wave:


Looks like a WINNER for chunky analog packs ! :bg:


$4!7 I gave away my REALLY chunky analog packs a while back...

...DAMN ... Never thought I'd need 'em.


Oh well, the new Tri-ang P-42, RELCO, Hornby Dublo Bakelite transformer setup has MORE than replaced those ol' fly gigs . . .

Maybe . . .


I do like the BIG lever $4!7 that Hal jazzes on about though !

That M.R.C stuff looks MADE TO LAST !

where is the second controller that fits on the right-hand side?
A complete unit sells for mere 79 quid.:Crazy:

Despite being totally ancient & powered by leaky 19th Century steam cylinders ...

... Woodie is a pretty 'Hi Tech Guy' ! :brill:


Hidden away inside his rusty ol' locomotives ...

... heavily disguised by the Zen Masters 'Industrial Apocalypse' look...



... are   MICROCHIPS !!   :shocked:







Some of these mooodern electronic marvels, do need a 'breaking in' period.

Of course, down Dallas way, the traditional methods are still the most reliable.


Here, Woodie is 'breaking in' a new Texas-Instruments TL07x series microchip.


Holding on tight to the wiring is vitally important & needs both hands.

In clenched teeth is a pre-made 'Pliobond' traction-tire...

...ready to be lassooed around the new locos wheels.



It's dangerous work ... But the ore-cars must be kept on the move !

I've been looking at getting my Old Analog Controller 'lash up' fixed properly for a while now !


In nosing through some old materials...

...I came across a very nice piece of timber, I cut ages ago, for something completely different !!


It fitted the parts perfectly, and looks really cool with my 'dusted-off' Old Analog Controller mounted on it. :bg:





From left to right ... 1950s,  1970s,  1960s,  I think.

Hornby Dublo A.C. transformer, RELCO high-frequency unit, Tri-ang Railways P-42 circuit-controller.


The history of mooodern plastics ...

... From left to right ... Bakelite,  A.B.S,  Phenolic-resin,  I think. ;)


Chunky stud-mount Schottky-rectifiers, courtesy of my Bulgarian contact in the Russian space-program ! ;)

3300uF 63 Volt smoothing capacitor.


Some adapting of the Tri-ang P-42 to come, leads need modding, for 'walk-around' styleee.

More soon  .  .  .

Victoria & Alberts braided cable steampunk controller (TM)

Could be a winner ! L:



I think I finally saw what Holster Hal might have been on about ?



I did search for some o' the ol' MRC packs a while back ...

... but only came across this dude today.

C'mon Si,
where's the nostalgia?
That's a state-of-the-art switch-mode 10Amp PWM Controller selling for as little as $248.- Adding a display would have breached the price barrier set by their sales dept.
It's all electronics and chips inside - urrps!

" C'mon Si, where's the nostalgia? "  :old dude:



Hi Helmut :wave:



OK ! ... I'll give you that one !! :f:

Perhaps I'm lusting after mooodern microchips after all ? :shades:



Now THIS one, IS the real-deal ! :thumb:

I'd consider parting with some serious bread for one o' THESE babys !! :cool:





Look at that beautiful patina !! :shocked:



I know that's normally reserved for the 'Antiques Roadshow' description of fine ancient bronzes.

But really, you just CAN'T fake that kinda RUST with a splash of paint & a few weathering powders ! ;)



Those decades of corrosion & oxidization are GENUINE ! :P



:pimp:



Si.



I wonder if it comes with the attractive green satin ?

I think Faberge Eggs would look awesome, displayed on such a luxurious fabric.

Could make a good field as well, with a drenching of Dull Cote (TM) & some died sawdust. :)

No, MRC's #501 always were that copper colour. Lo and behold - there is a pulse switch for those balky /PFM /FED /KK /Balboa motors that came with that Far East Brass.

Oh, BTW -they offer them with unmarred case for ~$8.00 on ebay.

@Si
you wanted LCD displays? Here it is.

THREE HUNDRED BUCKS ! ! !  :Crazy:  ... sspplluutteerr ...  :shocked:





I bet it's not even genuine Bakelite ! :f:  ;)


I bought one of those V/A meters for my DIY 'executive' S.C.R throttle ... For £1 ! ...

... & I've got a momentum/brake ! :P


I don't get it dude, why peeps gonna pay that much dough just to make a chu chu chug ? :dope:

This 'Lionel' controller looks like an interesting design. L:





An 80-Watt model, I believe.

Not sure about A.C./D.C. operation.

But I'm sure the intrepid modder could add a few rectifiers if needed.



:cool:

Si, that old Lionel pack is AC and would fry your butt if you crossed the wires! The old MRC's were state of the art and I still use an old one (MRC 1300) for the little Gila Tram layout. It has direction control, on/off, AND pulse or "full". Since I don't prowl the hallowed walls of evilbay, I imagine that some of those "sellers" want mas dinero for these old things. Somebody gave me the GT's pack along with a Marklin (AC) pack that weighs probably 20 pounds! A boat anchor for sure but I may use it for something. That MRC 9950 is beyond my scope, hell, I still use ancient r/c transmitters...but wait...I don't need no stinkin'power supply for my 35n2!

That old faithful Märklin 2x16V/50VA transformer is ideal to power my Intellibox and/or DCC-booster(s). Yes, I still operate DCC because not all my TT ga. locos have been converted to BPRC - sometimes there's only room for TPRC!

Howdy Helmut, the old power pack is worth keeping. Who knows, I may use it for lights, etc. or maybe build a small arc welder...I would send it to you but can you imagine how much shipping overseas would cost? A rubber mold for Daniel cost over $20 USD to send to Amsterdam and it weighed a fraction of what the power pack does! It would be cheaper for me to get a plane ticket & bring it...hey, that's an idea!!!

Sure, come over whenever you like. Once your eyes have adapted from the wide open spaces to little old Germany ( easily overlooked ), I'll even dust off my 27MHz Playmobil loco for you to operate!
No need to bring that Transformer- I have one already and cherish it.

Howdy Woodie :cb:



Thanks for the technical advice ! :shocked:
I'll make sure my wiring is tidy & my posterior well away from any terminals. (_!_)


Think SAFETY FIRST kids ! :w:


Don't forget to wear a mask also ...

... depending on how dusty your old analog controller is. ;)





Not bad for 32 Shillings and 6 Pence !
