Has anyone tried this or knows whether this is working?

My old throttle has given the ghost after 13 yrs and since I run a small switching layout with 3 loco's max, I don't really see the need to invest and/or upgrade. Just looking to replace the throttle.

Sent a question to MRC, who do not seem to respond so I wonder anyone here might know whether I can add the newer throttle to the older command station to get back up and running again.

Many thanks!

I have some older MRC tech4 200 throttles and the DC ripple causes annoying buzzing in my HO Kato locos, and only the first 40% of the throttle is usable before the locos run too fast. I've decided I want a simple potentiometer controlled transistor throttle. Voltage source will be a large 6V pure DC battery, output needs to be a variable 0-6 volt pure DC output. That means no DC pulse or PWM systems, and I'm not interested in DCC or dead rail. Load will typically be 50-250 mA, but possible spikes up to 1 amp.

I am pretty far along on track laying.  I seem to have a problem with the locomotive stalling. Since I have momentum on the CV it will role through it, there is just a momentary cut off of the sound and a jerk.  It is an Athearn GP with Tsunami and DCC.  I am running at low speed using a ProtoThrottle.  This can occur not only on turnouts but on a straight piece of flex. It  is not consistent on the same piece of track, sometimes it stalls sometimes it does not. I have done the following:

I have a pair of HO Kato engines with TCS decoders that were loaned to a 'friend' for use during an open house event.  Now that they have been returned for use on my NCE system, they don't light up, don't hum, don't nothing.
The borrower says he "didn't do anything to them."
Anyone have an idea what the problem is, and how to get them running again? Programming on the main and resetting the decoders according to the TCS protocol has not helped.
