Wiring Diagram for Protosounds Board?

Oops, just realized that he does NOT want ProtoSound 2.

I don't know of any available diagrams for original Protosound, but the wiring is pretty easy.

I know of no diagrams for the QSI boards, but they're readily available on the used market if you look around, so maybe a diagram isn't necessary.

Yes, he is funny that way.  He figures if he can learn to fix one, he'll start buying more blown board PS1s and fix them too.  This is a person who still in retirement builds old Penn Line, Bowser, English and Mantua kits including the super detail kits for the fun of it.  Wish I had that kind of time!!!!

Wait until you retire, lots more time.  However, I still don't seem to be able to get to all the projects I've lined up for myself.

Thank you!  I will check out the site.  I hoping in retirement I will be able to remember how to finish all the half done projects on my work bench that aren't done now! 

I buy DOA locos all the time....sometimes on purpose!  But rather than 'fix' old MTH boards or buy upgrades I just replace with a WbB board. These WERE easy to find and cheap.....but seems to have dried up....so I switched to Dallee which are close to the WbB unit price wise and about as bullet proof so far. Gut 'em and add a Dallee is the most simple.

PS wiring diagrams for all Dallee products are on his website. 

The big difference Dave is, you get no sound with the Dallee solution.  You can buy used PS/1 boards for less than the Dallee unit, and you can transplant the sound chip from the dead locomotive to the new board.

Can't help you with a circuit diagram, but here's a diagram of the pinouts. 

Well stated John. Except I gave up years ago. What projects I couldn't sell were introduced to the dumpster.

NOOOOO!  Blasphemy!   Put them on the shelf to fill up shelf space!

Maybe this will help.  I forget who did this but it is correct.  

Dallee has sound boards too......but that's not a important issue for me.

I DO NOT trust any used MTH boards......I have a voltmeter and a basic working knowledge but any and all MTH boards are beyond my pay grade.....I work within a structure I fully understand.....to old to learn a bunch of new electronics!

Just depends on what you want in an end result....I just want them to RUN!

Nice diagram Dave, I'm going to keep that one.

If you buy a Dallee reverse unit and a Dallee sound board, you'll have probably three times the money that just picking up a used PS/1 board will set you back.  I can afford to buy several PS/1 boards and still be money ahead.

Your method is fine, just not the way I'd do it.

Gentlemen - Thank you so much for the responses.  I will forward these on and report back with how the project goes. 

I don't do sound so I get out pretty cheap with the basic reverse unit. One thing about my hobbies be it model trains or muscle cars....I have to understand them 100% and able to service them 100%......and that's what's great...to each his own.

Dave, Shoot me an e-mail if you have a 4 speed 70 road runner for sale or know where one is.  G

Great info here guys!

I posted a couple of the diagrams from the thread in the technical documentation thread.  They're easier to find if they'd pinned.
