Aerovox Dry Electrolytic Capacitor

Hi,
Working on a Philco 39-116, It has a Aerovox capacitor (450V 16mfd) next to the mystery control relays. I'm uncertain just where it connects to, it has what appears to be a yellow wire and a dark green wire coming out of it...I can find similar color coding near the volume switch & motor...the schematic that I have seems to be more confusing than helpful. The radio works...somewhere along the line the mystery control went missing and some one cut the wires to this capacitor and another capacitor that connects to the inductive antenna, I've got a mystery control that will be restored also. Any suggestions?
Mike

Welcome to the Phorum!! If the schematic confusion is because you are having trouble reading the nostalgiaair copy of Riders, I'd order a set of schematics and info from Chuck Schwark for $7. Very clear and you'll get a large schematic. Someone who's had some experience with the 39-116 can comment further.

hi 61
I don`t have a 39-116
but I`ll try to help
looks like pos side goes to 94 150ohm resister
neg side goes to thinking motor ?
you could trace off 2a4g tube to the two .05 caps #97 & 98 and tie their

If that capacitor actually belongs there, meaning it's a replacement for the original Philco one and not just something some person stuck in there for an unknown reason, then it's probably dried out and open circuit anyhow and needs replacement yet again.

here is schematic
http://www.nostalgiaair.org/pagesbymodel...013266.pdf
yes aerovox is after market
but I believe part 95 is what he`s talking about it`s 16mfd @ 200v
any help please

Yes, (95) belongs there 
I've rebuilt a few Mystery Control Philcos, and I used new electrolytics and the radio worked well. However, I think if I had another one like this to work on and was a set I was going to keep, I would use one of the Solen "Fast" polypropylene capacitors from Antique Electronic Supply. Yes, they are expensive, but I've heard nothing but good things about these caps...install them once and they will outlast any electrolytic.

The 15 uF Solen would be a good substitute for the original 16 uF electrolytic.

Hello again,
Well after getting some better schematics it turns out the Aerovox Cap that I'm looking to replace is on circuit 65. The ground I 've got figured out, I'm just not sure where to solder the positive lead since the leads to the Aerovox were cut. Any help? thanks!

Cristina, I merged your post with your original questions about the cap to keep this thread together but I'm confused now. part# 65 is the voice coil on the 39-116.

Hello,
My error  it is part 69 not 65. The parts list refers to this as a condenser however I removed an Aerovox capacitor.....thought I read somewhere that there was an error on the parts list.
Anyway I've got a new Solen Fast Cap I've figured out the negative location but, I'm unsure which circuit to solder the positive side on. Any help?

Christina, "condenser" and "capacitor" are words for the same type of part. They were called "condensers" right up until after the Second World War. Even in the 1960s when I began to study electronics many of the old timers referred to them as "condensers," and, in fact, I still do very often, having begun calling them "condensers" because my early studies were from old books printed in the 1920s and '30s.

hi Christina
#69 is 25uf @ 300v cap
ground to connect where 4 resisters are #72
pos to connection or some place near it to tubes 42 pin 3 I believe
can you take pic`s and post it will help locate what it is and where
this way we can help you better

Thanks! the positive connection is exactly where I suspected just unsure of the pin. I'll take a look at the underside of the chassis
