Hello all.

I have just recently purchased a Radeon horn driver.

http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... 0160312542

I have it at home now, box arrived a little torn up but box was old and delicate. The driver and parts seem ok. Wire needs repairing.

So, how am I suppose to hook this thing up? I have I think a couple of options. The end result I hope to eventually play a list of mp3s via my computer.

But for now I will settle with hooking this up to one of my working AM radios.

I see it has a mock tube like deal that I'd guess is to hook up like some speaker tube amp. Thing I'm wondering is I see only 4 pins. I'd guess that AM speaker output tube amps normally have only 4 pin connections.

What I know about AM radio construction/repair could fit in a few paragraphs (in other words, not much).

What I wonder also is that shooting toward my eventual goal of playing a list of mp3s through the orthophonic.

Could I take output from one of my stereo amps (in mono) and hook it directly to the speaker?

But, that'd require that I cut the present volume control out. I know the thing is an antique and should not be altered, but I would see about removing it from soldered connections inside the device. That way it could be restored to fully original if desired. Besides that, the wires are in need of repair/replacement maybe.

The thing about that is I don't know if I'm mixing apples and oranges here. The output of one of my typical stereo amps is pretty loud, but is it enough juice to drive a 1920's designed speaker driver?

I'd guess other options are to use AM radio and buy some USB AM transmitter so AM radio recieves that and pumps it out the horn.

When I finally conquor this project I hope to be able to listen to whatever I want (super long playlist) of mp3s crankin out of my VE8-35 orthophonic.

I'm hoping that the orthophonic exponential horn sweetens up the highs and lows.

I think i'dll be sweet...!

:D

I know a guy who can help you with that. Wyatt Marcus, phonovoic on ebay. If nobody else comes up with his contact information I can probably find it.

Wyatt recently resurfaced on Matt Browns Edison Board under his moniker MicaMonster.
Why do we need signatures when we are on a first avatar basis?

Hi RJ,

That is in nice shape! I may be way off base, but I think that works the other way around, i.e. to play your Victrola through your radio. I think the four pin plug replaces the (detector?) tube in an early battery radio and the driver fits on the tone arm and takes the place of the reproducer. Is there a needle chuck on the driver? Is that what the setscrew is for?

That said, I have seen a couple of similar devices around, but none as nice and complete as yours. Good luck!

Regards,
James H

It may be faster to e-mail him (his e-mail is on his web site), as it doesn’t seem like he’s tremendously active over at the Edison board.

Unfortunately, I know literally nothing about radio from that period.

Based on the photos, though, it does look like you might want to replace the wiring...although they said they tested it.

This is what I thought, too, from looking at the last picture. The plug device likely replaces the first audio or second detector stage tube.

Yes, you guys are correct. Well, back to the drawing board. I just recently purchased some bass speakers including tweeters. I'm going to try building a box to insert tone arm in.

Least with standard 8ohm speakers I can directly connect to my amp and feed that with laptop mp3 list.

Not sure how it's gonna work but hey...

RJ

Basically, it sounds like you’re wanting to do something like this (but not with an iPod or iPhone). It shouldn’t be that hard to put speakers in something that you can connect to your tone arm. I think the biggest concerns will be making sure that you don’t construct it in such a way that you get buzzing, and to have a good seal where it connects to the tone arm.

Unless you have a computer that you want to tether to your amp (e.g. the output from my desktop is the most-used input on my stereo receiver), you may want to look at the music sharing features of Apple’s AirportExpress, since it could be plugged into any outlet and provide the Line In on your amp, so that you don’t have to run a wire from your laptop to the amp. Plus, it’s very easy to set up and use.

Let me know if you have any questions, or if I can offer you any suggestions for your project.
