Hi,
If you could take two pictures, one of the top of the whole chassis straight on without the valve cover and one of the underside straight on that would be helpful. With your smaller pictures I'm having trouble telling which side is which.

I have an early model 70 chassis that I've been using for parts and it has the coils but I know that the antenna coil is bad, both primary and secondary are open. The other two coils I haven't removed or checked. I you would like all three their yours for the shipping costs. Both the model 70 and 71 share the same IF frequency so they should be usable in your set.

Terry!

Valves!?
Next thing we know you will call your front hood a bonnet!

Blimey, you better stop that bloody poppycock right now, old chap!

Tnx

That chassis is pretty much useless without the coil shields. Those were spun on and you can't replace them.

This one looks like it has L bracket to hold them on.

I see your point. I've never seen coil shields like that on a 71 before. They were obviously square, not round. Very strange.

Hi Bartolome,
The only correct valves you is the 39 (also called 39/44), 36, and the 80. The rest have the wrong heater voltages to operate in this set.
Here is the service information   http://www.nostalgiaair.org/pagesbymodel...013837.pdf
You may have to make the metal coil shield as it is not common the the model 70. If you would like my parts chassis you are welcome to it. To cut down on shipping costs I can remove some of the heavier parts that are left. With this chassis it has the coil shields, they are stamped into the chassis and don't come off without cutting them. I took a look on the net for a 71 set with those square shields and could find any,was your set built in the US?

If you need a source for the other valves I have spares too if it makes sense to ship form here.
Tnx for the picture update!
