Slowly tinkering away with things as and when time permits.

This is the finished Audio Module, now fully cleaned up and rebuilt.

Exterior before cleanup:

And how it looks now:

Interior before cleanup:

And how it looks now:

All fully tested and working. Just need to fit a volume knob.

Still not sure whether to replace the labels on the lid. If I did, I think it would be indistinguishable from a new one :lol: :lol:

Thank you for the kind comments.

Tonight's success was with the Motion Control Module.

This is how it arrived home, fused into a mess of parts, cardboard, melted plastic etc.

These pics show it once I had removed it and broken off all the stuff stuck to it.

You can see a clean green area on the the PCB. This is where something had snagged around one of the surface mounted capacitors, which was then pulled from the board as I was untangling it. Fortunately, it stayed in the case. You can see it in the upper right hand corner of the PCB, near the first spade connector.

And these pics show it as it is now.

I have blurred the chips and relays to prevent any industrial espionage.

Unfortunately, during the cleaning process, and I had to be quite vigorous at times, one of the legs of one of the MOSFETs broke. When I did the first power up test, everything looked OK, but when I tried it with a motor, that side failed due to the current overstretching the other MOSFET. Fortunately, the built-in current sensing circuit kicked in exactly as designed and prevented any cascading damage to the board.

I ordered four replacement MOSFETs, soldered them in tonight, and have tested both sides with a motor and both sides now work perfectly.

Wow... I assumed that was a brand new board from Armortek....

It's tough enough fixing metal and castings and industrial-age parts.

To be able to recover a circuit board and all the IC components.. is unreal. Remarkable!

Well done! That is taking restoration to a whole new level!

Cheers,

RPR

Blimey, is it January since I last posted in this thread ?

I managed to get most of it the hull prepped and ready for paint, and made a start on priming the suspension bars etc, then decided to remove the red oxide primer and have the inside of the hull in just plain white. Then the weather turned nasty, I was made redundant and, now I'm working freelance, I've not had any spare time to work on it :-(

The weekends that I'm not attending shows, it seems a remarkable amount of my time is taken up with cleaning, shopping, washing etc.

First World problems though I guess :roll:

Not to mention a certain “Centurion bridgelayer with Mo 6 bridge”. Outstanding skill Adrian to restore those units. Really inspiring.

In that case Adrian my hat's off to you for that bridge layer. Are those hydraulic jacks or screws jacks?

It's all hydraulic, just like the original. It took me a while to work out how (and why) David had plumbed it in, but it all works a treat. Operating pressure when raising and lowering the bridge is 100bar (1500psi).

I'm investigating fitting hall effect limit switches, to prevent any re-occurrence of my poor operational skills causing the ram to relocate itself.
