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'...

...rather than 'Plug & Pray' !

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.

Do you mean 'Tuxedo Junction, saga of an H0 empire' featured in MR? The protagonists  ( if my memory serves me well ) - Hal, Ernie, and Caroline?

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 !


:moose:

Looks like top-notch quality made kit ! :shocked:

Built to LAST !

@Si
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  .  .  .
