Hi guys, I recently purchased a Spectrum 36 ton Shay. It has an old PH Hobbies Inc. Sound card in it, marked (SH) which think is for Shay. I believe it is a S4004 sound card? I was able to charge up the old battery, and it's holding at about 6volts.
It has two magnetic switches attached, which are either whistle or bell triggers? Would anyone have a installation manual for this sound card? I would like to see if it actually works? Thanks for reading Arnie.

Need a pix as there were several versions of the PH hobbies sound boards.

Hi Greg, yes, my sound card looks the same, as close as I can tell, to the S4004 card you have posted except your picture shows a black tab in the center of the card with THM-6043 stamped on it, mine does not have that tab, and I can't see below the tab to see if mine is the same? All the items around the edges look the same.

Hi Greg, I'll try again? Yes, my sound board is pretty well the same as the S4004, except your picture shows a black tab in the center, which I can't see by to compare the components underneath. Mine sound card does not have that black tab?

That black tab is a clip on heatsink for the LM317T voltage regulator. They get hot easily. Would not be a bad add-on for your board.

go back to my page, you will find a connection diagram for the 4004 on that page now.

Send me your email, I have a pdf "manual" that might help also... not great but some more help.

There's a reply box at the bottom of the whole thread with a "Post Reply" in a BLUE button that does not quote your post.

If you highlight a sentence it will pop up a "Quote or Reply" pair. Reply has the same effect - it opens a reply box with your highlighted text in a Quote pair. Select "Quote" and it saves the text for later - to be inserted as a Quote in a future reply.

Confusing, right?
