Hi Ed;
Thank you for visiting NoobowSystems. Apparently the NAV-555 is designed by Koden. When a Japanese adventurer Ken-ichi Horie sailed from Japan to San Francisco across the pacific on his yacht "Marmaid" in 1962, he used Koden KS-357 portable direction finder which is the predecessor of the NAV-555. Celebrating his achievement of 40 years ago, now Mr. Horie is sailing again, this time with a modern satellite navigation system.

Greetings

Hello Chris;

I checked with my TE-50. The diagram in the manual only shows symbols, no spec of the transformer, as you mentioned. However, from the diagram we can well guess its spec. Unfortunately, I think it is very hard to find. It is an auto-transformer for 115 volt input, having taps for each heater voltages as follows; A-&-B for 1V, C for 5V, D for 6V, E for 12V, F for 25V, H for no connection, and J for 115V. Alternative is to use 12V heater transformer with center tap; you can wire only for "D" and "E" so that most of the tubes can be tested. AC power voltage is to be directly used as plate supply (identical when the power switch is at HI).

Hope this helps, and good luck.

Fascinating place! Wonder if anyone can help! I have an old LAFAYETTE Tube tester model TE-50. Does not work because transformer has been fried!! The only schematic I can find has no part number, type or even voltage specs off the transformer. Also there are no numbers, data, parts number, etc.on the transformer. Anyone know of a replacement transformer, part number or even just the voltage specs of the tranformer taps. May not be made anymore but hoping I could find a replacement--would bring life back to an old piece of equipment. Thanks for any help!! ChrisL 3064@aol.com

Broken ICF-7600D???
Can anyone help? I really enjoy my ICF-7600D but it recently developed a problem. When I turn it on it sounds like it is quickly scanning through a band then no sound at all! Any experts out there care to share an idea?
Thanks,
Bob

Hello Dan,

I have been enjoying your pages quite a bit! It's very entertaining and informative to read how technical problems were diagnosed and solved, I always learn a bit more about troubleshooting from this.

I will remember to read them again when I start restoring my Hallicrafters HT-34 (someday in the future! g)

Dear Dan,

Thank you again for your kind help with my Sony ICF-5900W. Your email, combined with your fabulous web site, hit the mark. I did a complete alignment of the 5900 based on your information and everything worked perfectly. Perfectly. What remarkable performance I now get out of an "old" radio. I don't know when I've enjoyed a web site more. What you are doing is fantastic.

I sent the information about the ICF-5900W to two more owners/users and both of them are very excited about "renewing" the 5900. And I might add, both of them love your web site.

Keep up the good work.

Sincerely yours,

John English

Hello Robert and Gururaja;
Thank you for visiting NoobowSystems. It's always fun to receive comments from all over the world!
For 5900's pop-up antenna, new replacement is no longer availabe from Sony service, according to another Sony fan in Japan. I read that one gentleman mastered rebuilding it by "transplanting" from other radio with similar antenna. I hope he will begin his rebuilding business, but it looks real time consuming job.

Hello,
For years I try to get in touch with someone who can help me get a new antenna with the pop-up-mechanism ( do not know the name) for my wounderful ICF 5900.
Is there any ICF 5900 fanclub or collector-club which do spareparts and can be helpful in other things? Is there ANY SONY COLLECTORCLUB IN THE WORLD FOR SHORTWAVES AND RADIOS?

Kindest regards
robert

There are six (6) tuning ports under the rear cover of the Sony icf-5900w. What do each of the six ports do? How does one align this fine radio by using the six ports.

Any help will be appreciated.

Thank you.

Hello Richard;
Congrats on your SB-34. When I was in California before, I did not have a valid license nor a dummy load so I didn't test the Tx. I think yours is not bad if you get 45watts, but not sure. In the manual they say some excuses on its power spec, so I would not pursue the maximum power from 34 (it would be fun, though). Also I heard weak Tx on many 34s, guessing the problem would be common and not tubes themselves. I'm still learning basic electronics, not knowing exactly how to improve the 34's AGC. If you try something, please tell me the result!

Dan: Thank you for the information on the SBE 34. I have just acquired one through a trade. I am sending all for the manuals in order to do a proper alignment. Your site was a wealth of information regarding the ciruitry of the volume, rf gain, and i f gain. I am wondering if a reostat/variable resistor could be put in one of the speaker leads to control the volume and leave the gain all the way up on the volume control on the front of the radio? Do you think that this might work? How much power does your put out. I am getting about 45 watts or so on "tune". Do you think final replacement would be in order or not? Do you live in Japan now? Apparently at one time you were in the USA. Thank you, Richard Pumphrey, wn9ddv

I think I over loaded my receiver by plugging in too many things into one plug. The AM FM radio receives nothing, but I can play my CD player. Can this be fixed?

I own a Hammarlund HQ-170A and have just got the IF alligned correctly. How can the Audio output be improved? The schematic (your web page) shows a corrected circuit for V16 and V15, but I can not read the text (sorry can't read Japenese). Would you consider sending English text to my E-Mail?

Very nice Web-site and excellent refurb projects, thank you, 73.

fantastic to see your site regarding the Sony 5900, my friend just acquired one at a weekend market for $20US, I'm going around to see him and teach the operation of the Xtal marker.

I have alot of Sony digital radios, but mr favourite is the National 2200 which I found at a trash market . It was so dirty I couldn't recognize it the lady wanted $1.00 and mentioned that it was a very good radio when they brought it!!
I gave her $5.00 because I was a bit embrassed to get such a good radio.
It wasnt working but it only took afew minutes to locate a crack in the PCB board one side of the power switch.

I have the original RF2200 sales brouchure which is great reading if interested I can scan and send a copy to you.

Well done and keep up the good work

Hello Al;

Thank you for visiting us. The ICF-5900W schematics which I purchased from A.G. Tannenbaum contains the alignment procedure. Please see below my comment. Seems like most of the surviving 5900 require the realignment, at least local oscillator in order to correct the main dial. I did not have the alignment information when I first acquired the radio so I removed the dial mechanism and mechanically adjusted, which turned out to be not a good way.

BTW, does anybody have a copy of Panasonic RF-2200 schematic? I received an inquiry from Australia but I don't have one. Unlike U.S. we have virtually no manual copy service here in Japan. Sony, Panasonic, and other firms are still in business so I guess Japanese users are hesitating to put schematic scans on the Net. I hope those manufacturers, especially Sony, are responsible to provide those information because they made us such enthusiastic. :-)

My ICF-5900W is in mint condition except that it needs realignment. What are the functions of the six (6) tuning ports under the rear cover? Where can I find alignment instructions for the ICF-5900W? Does anyone know how to align this wonderful receiver?

You have an excellent web site -- most informative -- most helpful.

Can you supply information on aligning my export version of the SONY ICF-5900W, specifically as to what the six (6) tuning ports under the rear cover do? Where can I find alignment instructions? Except for the need for alignment, my ICF-5900W is in mint condition and it compares very well with my ICOM equipment drawn from a later generation.

Thank you again.

Sincerely yours,

Hello Steve;

Thank you for visiting us. It's nice to hear your interesting story. I hope I could provide much more information of 5900.

I purchased a 5900W's schematic from A.G.Tannenbaum. Here is their URL:

http://www.agtannenbaum.com/

As I wrote in my 5900W page, it does not have a diode to protect reverse connection. It might be challenging to fix it, but I hope your good luck. Please tell me if you find which parts were damaged; I'll post your experience in my page so that other unlucky guys would thank you. :-)

In these 3 days my Collins 51S-1 keep shaking its S-meter needle with anger for the evil act. Hope you and your family, as well as any person who once visited our site are all right.

With regret and deep sorrow for the innocent victims;

dan
