I am desperately trying to learn this hobby, and learn how to fix up some radios.

It's not going well.

I am in desperate need of local help, or everything I touch will turn to a pile of useless parts.



Please....I really do want to learn, but I cannot figure this out.


Please, for the love of god, someone help me

It would be helpful if you posted your location.

My apologies....got confused with another forum that shows that automatically.

I'm a bit in full blown panic mode as I have a radio in pieces I've invested time and money and time into, and really don't want to destroy it, but this is getting out of hand rather fast.

I'm in Attleboro, MA.

If you can link to others in your area in the same boat,
and there is no radio club available, ask your local
Community Education centre to find an instructor.

If your group can generate enough interest to
pay reasonable registration fees, that can
cover the wage of the instructor, the School
usually will provide facility and indemnify
the teacher.

Here are a few informative restoration videos from Paul Carlson.

Paul has a fair amount of haters on this forum!

I am in S. Dartmouth, maybe I can help be a "LIVE" Elmer!

Traffic is suicide but I am free this weekend. I do not travel, so you must come to my lab and bring your dead meat and its Viscera.

BTW Is this a phono that is to be a Christmas present so the urgency?

PM me, I will forward email and phone...

FWIW I do not do Euro sets, do not have docs or tubes in stock... No carts, needles or idlers in stock.

GL with a video :roll:

The urgency was just after years of doing nothing, decided today was the day, and once I'm digging in and forgetting things, it's like.....if I don't get this to some sort of state of something today, it'll probably be toast.

So there's no Christmas urgency, other than the piles of Christmas 45s that will be out of season once this project is finally done, but perhaps I'll have something working for next year.


I miraculously have this in a semi-working state. I replaced the capacitors I could see. Probably very poorly as my technique of getting into tight spots with a soldering iron is not quite there. But....I decided, what the heck, what do I have to lose at this point, so after changing the capacitors with the exception of that cardboard tube that I"m not sure how to deal with properly, lets plug it in and see what happens.


It came up, and I got a slight crackling with the turn of the knob.

So...I closed it up and put it together, plugged it back in, turntable turns up, changer drops a record, and I have a very loud hum, and sometimes even get a little bit of audio when I fiddle with the knob, although the tone arm is having some funky issues. I did lubricate everything carefully, but....eh, first time doing anything like this, so I suppose getting it to a state where you can still get sound for just a moment when fiddling some knobs, and a tone arm that isn't moving as freely as it should, isn't the worst place to be for a first attempt.



Busy this weekend, but will PM you. Now that I have this in a state that it can be set aside, I can breath, and make plans for another weekend so we can dig into this more, and I can start learning more and get better at this stuff.

O.K!

You have two posts running on this topic... But I got the message.

You have either improperly connected the replacement caps (backward or wrong lug), they are the wrong caps, made a short during the repair, wire clippings, solder blobs wire whiskers touching left the old GL (triple cap in one package) still connected or there is leakage in the output tube that only a tube replacement will fix.

Oh, you done good getting the changer going :D

GL

for now

How about stating what the problem is?

That cardboard tube needs its guts replaced. Usually you can bypass it with new 'polarized electrolytic capacitors'.

The other thread you've started can be the place to continue the technical discussion.

viewtopic.php?f=9&t=367721

If NEARC club meeting is too far, perhaps there's a member living closer to you.

Radio restoration isn't easy. It takes knowledge and experience. Time and patience. Patience with yourself and self-belief are important qualities. I have failed with radios and felt pangs of disappointment and even anger. I had successes too. Remember an advanced radio engineer may have had years experience as well as professional training. Some of us started out just wanting to learn. I recommend Chas Miller's Vintage Radio and Audio book as the focus is on repair. As to capacitors in many cases you can use film capacitors so no need to worry about polarity. The big 8 or 16 microfarad power capacitors need to be electrolytics, however. Make sure the voltage rating is correct. Plenty of leeway. I often used wima film capacitors rated at high voltage for tube work. As to soldering, personally I make do with multistrand but cut the end lead very short and use lots of solder heat. Tin the wire as well as scrape old lugs clean. Thin wire solders easier I think. Sometimes access is poor and frustrating. Very often I would totally dismantle to gain access as I figured it saved time in the long run. Yes, I have had to redo my soldering and have made a mess of it. Improvement takes time and patience.

NEARC/NEVEE does not have meetings but flea markets,. Some training is offered but 1/1 is difficult at best in the two hours and the many members present...
