Hello everyone,

 

         A very nice fellow forum member and good friend asked me to install, a Fat boy speaker in the boiler area of his JLC challenger item number 6-28099. To say the least it was a mighty task, but a lot of fun to do. I also installed two new Fat boy speakers in the tender, upgraded the smoke unit, and upgraded from 2 to 4 chuffs. Many parts had to be purchased to accomplish this speaker upgrade.Also many wires had to be spliced and rewired and I had to relocate one circuit board. The project turned out really well, the sound is much improved ( not louder ) but more robust and evenly distributed. I only have pictures of the project right now, there will be a video to follow.

 

 

Thanks for looking

Alex

Alex;

Great job as usual!

I admire your tenacity; I would not have had the patience.

A couple of questions if I may:

I assume the two 8 ohm speakers are wired in series, and the single 16 ohm boiler speaker is wired in parallel with them, to result in an 8 ohm impedance?

The clear plastic baffle for the tender speaker; is it a standard Lionel part?

I have not seen one of that size. Do you have the PN handy by chance?

 

Thanks as always,

Rod

Hi Alan, Dave, BF166, Brian, Joe, and Rod, for the very kind words!!!!!!!!!

 

Rod, yes you're totally correct the speakers are wired just like you said.

As for the speaker enclosure it is a Lionel part, see the info below. You must use this bottom base plate with this enclosure

Alex . . . . 

The Navy just announced this new "Stealth" Destroyer which I would like to add to my bridge scene in O Scale with Six fat Boy speakers and a missile firing system. You could bash the old Lionel firing system and I could squeeze this in right next to the tugboat.

Can you have this done by the weekend? Thanks !

Alex,

If you finish the Destroyer early, I also want a machine to power the Bascule Bridge.

I came up with this simple design that you can knock out by . . . . um Saturday?

Yep, having done a similar complete electronic overhaul on an older Lionel Hudson I have great admiration for those with the patience and expertise to tackle these sorts of projects. As usual Alex you've done a bang up job here, and I'll add my shout outs to John and Marty for all the help they've given us!

Ok thanks for the info Alex.
Rod

 

Good morning everyone,

 

Thank you for the kind words!!!!!!!!!!!!!

 

Gerry O'hara , it's great too hear from you. Where have you been !!!!!!!

 

Marty couldn't do this without the help from you and John

 

Pat hope too see you at Allentown

 

Doug your project on that GP35 was outstanding. The best word for it is WOW,

 

I might as well tell the truth the reason why there's no video yet, is because when I test ran it I didn't realize I left the tether between the engine and tender

to long. What had happened is it got caught on the point from a switch track, and ripped the tether in half. So needless to say I'm waiting for another one.

As soon as I install it I will post a video.

 

Thanks,

Alex

 

 

 

 

 

WOW Alex, ripped the tether right in half!   I guess that's one vote for a wireless tether.

 

Chuck, the chuff on most of these locomotives are determined by a cam on one axle that actuates a microswitch, it yields two chuffs/rev of the drivers.  Alex previously had added to lobes on the cam using JB-Weld on another project, though he didn't mention how he did this one.  I've looked at the cam, but taking that all apart to add material looked like a PITA, so I've never done one that way.   That's why we call him the Smoke King.

I am the owner of the challenger and yes the sound quality IMO is much improved. You get a stereo effect with the speaker in the boiler. The four chuffs really improves the sound overall. 

 

I am am very happy with the results of the upgrade. Alex is the man!
