Voltage too high

I have replaced all of the caps that show actual pf values and it has made a difference. The dim bulb tester is not as bright but still too bright. I now have 5 left that have the weird numbers on them. They are physically the same size as all the others. About 3/8" diameter and 3/4" long and solid black. I have not changed the two lytics yet. Voltages are marked so I will be sure to use the correct ones. There are two of the black caps with 6K8P x.4 on them so I thought maybe I will take one loose and see if I can get a value on it. I have a meter from Harbor Freight that does measure capacitors. Maybe I can compare the reading to a new capacitor and figure out the value and try one and see what it does.

It would be really weird, Denver, if these are resistors since they look just like all the caps that had values on them. Maybe I'll leave them alone for now and just change those two lytics I found and see how that does. Thanks for all the help. It has been a learning experience.

Philips did use cathode resistors. Part cap part resistor.
And they were black. Look up cathode resistor.

Found a service manual free if you join[url]www.radiotechniek.nl[/url] lots of philips and other manuals.

Thank you for finding this Denver. Very clear documentation even if it is in German. The schematic and top & bottom views are very clear. I will study it along with the part numbers. Should be very helpful to anyone else reading this to download schematics. Very easy to register also. And its free!

Thanks again...will post any results on this.

There is a link i seen somewhere. On the site translate to English . Thanks sure took me some research to find this.

It does appear that line voltage is too high for the set or for some components; however something you said does not ring true:

You said it's worse when you go to 125 volts on the line voltage selector. When you do that, it actually gives the set less voltage than when it is set at 110 volts. Did I misunderstand?

Actually, Mr. Corbin, It was worse sounding when I switched it to 125v. It created a low pitch squeal regardless of any station it was on. This was before I had changed any caps. I have a few more to go then I will try it again at 125v and see if its any better. It seems to improve the more caps I change out. I did not know that changing to 125 actually lowered it. Thanks.

To Denver: Yes I have also seen something on translating to English. I'll look for it later. It really doesn't impair reading the schematic too much though. The part numbers are there with values which is really helping me figure out whats what. I'm not the greatest at reading the schematic but the diagram showing the components in their place really helps me locate everything.

Finally completed replacing all capacitors. Still pretty much where I started. Plays great as long as it is plugged into a dim bulb tester with a 60w bulb. Bulb is dimmer but still on. Dimmer still when I set the radio to 125v. But plug it directly into wall outlet and as radio warms up a loud squeal starts and continually gets louder along with the station reception. And for some reason I lost reception on FM. Before I started FM played fine. I've only checked a couple resistors so I quess thats my next step. So what would the wattage be on a resistor over an inch long? 5 watts maybe? Could a tube cause this situation. I've tested them on a simple emissions tester and 3 of them where practically dead. I replaced those 3 but could the rectifier be allowing too much voltage to pass thru?

I doubt the rectifier.
You have to be neat in wiring, and, as close ot original as possible.
Hope you didn't use any disc capacitors.
Did you replace electrolytics?
Bill Cahill

Iam with bill on this . Sounds like the electrolytics to me .
You do have polarity right. And close to the original values.

Replaced all paper caps with the yellow film caps. On a few of these I was slightly off value such as for a 0015 I used a .001, for a 0018 I used a 002 for a 0039 I used a 004. Other than these I was dead on the original values.
On the electrolytics it had three 50uf/300v in a can on top of the chassis. I did not restuff the can but wrapped together three 50uf/450v and mounted under chassis. I did watch for correct polarity. I grounded all three together to a tab on the original can and cut loose the wires to the old and connected to the new 50's.
I also found two electrolytics under chassis. one a 10/70v that I replaced with a 10uf/160v and an 8uf/300v that I replaced with an 8uf/450v also being careful of the originals polarity.

Could I be wrong where I grounded the three 50's? Wouldn't the originals be grounded to the can and not the chassis? I'm going to double check this part.

Connecting the negative leads of the new electrolytics to the negative on the can is correct.
I'm most concerned of neatness of wirring. Next point, if one of those caps connected to oscilator, it might have needed to be a mica.
Other than that, are you getting stations? Is it squeling at all volumes, even all the way down?
Does squeling vary with tuning dial?
These types of things should help pin point if squeling is amplifier related, or radio related.
What type nos of tubes does this set use?
Wirring in some areas is crittical, and, occasionally the type of capacitor.
Make sure you eonnected every connection in the correct place, and,no short circuits.
The fact that you said fm is now dead, makes me suspicious.
Could be something got mis-wired, or, a short. Happens to the best of us.

Bill, after reading your post I turned it on and found that the squeal will go away if I extremely fine tune onto the station. If it is slightly off the squeal is loud and goes up and down with volume but as I precisely tune onto another station it goes away. The eye tube does not change on or off station just stays burning bright. I try to keep leads short as I replace the caps but I did add wire to the three 50uf electrolytics. There are ten tubes-ECC85, EBF80, EF85, EBC41, EL84, EABC80, EZ80(replaced with 6V4), EL84, EZ80, ECH81(replaced with 6AJ8) plus the EM80 eye tube. All originals are Phillips made in Holland. I will go over everything and look for any mistakes.

First, have you tested the tubes?
This sounds like either a bad tube, or, radio needs alignment...
Have you checked voltages coming out of B+ supply? Make sure they are what they should be at our line voltage.
If not, it's a power supply issue.
If they are close, and, I suspect they are, you need to realign the set according to correct alignment proceedure.
This is not unusual.
At lower voltage, the radio frequencies will be different.
Sounds to me like an alignment problem.
Bill Cahill

Thanks, Bill I'll keep at it. I'll check some more resistors and maybe substitute tubes. I have checked them but only on an emissions tester. My neighbor is German so maybe she can translate for me the alignment procedure on the schematic sheets and I'll check voltages. Thanks for your help. I've only been doing this for a couple years so this one has been a learning experience.
