In the dog house

[Eric H]

I've done two of the 103 chassis, they are great sets and very easy to work on with lots of open space under the chassis..

Be very careful of the dial setup on them, the gears gum up with old grease and you can easily strip them if you try and force it.

They use a delay relay to hold off the B+ until the tubes warm up, the winding on the tends to open up, both sets I did had bad relays.

You can just wedge the relay shut to work on it but it can be replaced with a modern 5000 ohm relay. I just take the coil out and put it in the old frame.
