[Solved] Atwater Kent model 325 capacitor question.

Resistor wattages and color coding are shown in the service literature. It says the drawings are actual size, but the scale probably changed when they scanned it into a .gif file. Never hurts to go with a bigger wattage if you are unsure.

I have an Atwater Kent 325 I’ve been meaning to restore for years. It used to work, but would lose volume after a short period of warmup time. I remember not being able to find a tester that would test the four pin tubes or being able to find replacements for it, but that was before the internet. It came from my great grandparents, so I guess it is sort of a family heirloom.

@robotwizard So far the info I found on this radio online doesn’t include a parts list or info on the resistors except for the resistance value.

@rs-electron I posted it at my google drive in my last post. There’s about 2/3 of a page on resistors above the knob part numbers

@robotwizard Link has restricted access.

@rs-electron don’t know why that was set, I was able to change it so try it again.

@robotwizard Thank you, that is the info I was looking for!

@rs-electron Keep us posted on your progress with it. If you haven’t had it working yet, I think you will be pleasantly surprised at the sound these things had. I used mine for several years before the problem showed up. It had a nice bassy sound with the big speaker. Atwater Kent certainly took pride in their products. I was always impressed by the fact that the inside of the radio was just as much a work of art as the wood cabinet. The black krinkle finish along with the gold colored parts are a nice touch, as well as the way everything is finished off and organized.

@robotwizard Will do, after recaping and rotted wire replacement it’s working. Need to replace out of spec resistors and do an alignment yet. Also tuning knobs are missing and I will have to hunt for a replacement set.

I know I might sound silly asking but, how did you actually know for certain that they really are resistors and not something else? Did you do a resistance test on them to see if they conduct and what value they have and also managed to identify them in the schematic (if you have one) ? The reason I’m saying it is because some years back, (10-15 years back)  I came across some German vacuum tube radios (cannot recall the manufacturers name) as well as some vacuum tube TV.s that they’ve had such (identical looking) things in them but they were in fact color coded quick acting fuses not resistors. I don’t know, is hard to say but in case you haven’t measured them yet, they could even be caps as well as RF chokes who knows. I’m kind of curious myself of what they really are. Hmm…

@ovi4 I have the component map and schematic for the radio. Just needed info on the wattage of the resistors. I have that now thanks to @robotwizard.

@rs-electron So they really are resistors after all. Cool. I’ve actually tried to access robotwizard’s linked documents before attempting to write my comment  but for some reason the link just wouldn’t get me anywhere. Then now, after reading your answer have tried the link again and it worked this time. I’m glad you’ve found the answer and tnx. to robotwizard for sharing the docs with us.

It shouldn’t be too hard to do the math and figure out what the original rating was.  You can always oversize for wattage ratings. 

@timfly True, Have the info needed now.
