Can I use the H-13 speaker? - jeremyfries - 07-01-2010
While scrounging around for parts in the dark corners of local shops today, I picked up a H-13 speaker with a transformer marked as 32-7078N. Can anyone tell me what the field coil resistance and voice coil impedance is supposed to be for this? I'm wondering if I'll be able to use this in my 40-180 project....

Jeremy, The H-13 speaker has a field coil resistance of 1125 ohms and the voice coil is 1.11 ohms. I think all the radios that used this speaker had type 42 outputs (push-pull).

Thanks, Steve. So it won't go into the 40-180. Ok, I guess it goes to a different project!

Jeremy
What size speaker do you need for your 40-180?
I have a couple 1940-41 Philco console speakers, and I think one of them will suit your needs perfectly. I'll trade you one for that H-13! I could sure use it.
LMK. Thanks.

Well thank you, Ron! I'd be only too happy to organize some sort of swap. I need a 12" speaker, field coil resistance of 1100 ohms, etc like the original 36-1479 or perhaps a 36-1528, for example.
The H-13 definitely needs some TLC...there are a few tears in the cone, the cords are cut and it needs a good cleaning. As soon as I can find the digital camera I'll upload some pictures for you so you can see exactly what I mean.
Thanks!

Hi Ron, here's some pictures of the speaker. Let me know if you're still interested!

Thanks for the pictures, Jeremy.
Can you check continuity of the field coil? If it has continuity, consider it a done deal.
I'll write more later when I have a little more time. I do have the speaker you need, btw.

Hi Ron, I checked, and it does have continuity. It's yours!
