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 thanks for answering I'll put some more photos where they are missing if the three coils. Greetings. (You might be interested in the coils and plugs you have to save this radio)

RE: Philco 71b ?? - Radioroslyn - 10-23-2016

Could you also list the valve # that are in your chassis?

Tnx!

RE: Philco 71b ?? - Bartolome - 10-23-2016

7 valve. Thank you.

RE: Philco 71b ?? - morzh - 10-23-2016

Terry!

Valves!?
Next thing we know you will call your front hood a bonnet!
A bit over 200 years ago you'd stand accused of high treason!
Blimey, you better stop that bloody poppycock right now, old chap!

I understand that it has 7 but what are the specific # on each tube, like 80, 42, 47, 24A, 36,78...

Tnx

Oh that's right I should have asked him to remove the screen from the rf toobs.

RE: Philco 71b ?? - Ron Ramirez - 10-23-2016

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

RE: Philco 71b ?? - morzh - 10-23-2016

Better. Icon_lol

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.

RE: Philco 71b ?? - Bartolome - 10-24-2016

It may be that they have changed.
these are the valves that had put. Greetings.

1-39
1- Crosley 124
1- Pilot P-236
1- Arcturus 124
1- 80
1- Silvania 43

RE: Philco 71b ?? - Radioroslyn - 10-24-2016

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/837/M0013837.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!
