RE: Philco model 610 rebuild - by Tim P. - TV MAN - 03-27-2014

I am near completion of the recap. I lack the 16mf and micas - in the mail. I had read a post by Gregb
http://philcoradio.com/phorum/showthread.php?tid=8852
where he had restuffed his wax capacitors. Since I didnt think those new yellow replacements would look right in this old radio, I decided to give it a shot myself.

Here are the results:

This is the big .1 mf cap you see first thing when you flip the chassis over.
   

I warmed it in the oven for about 10 minutes. Using old gloves, I pulled one wire with pliers and got part of it out. Then, ofter re-heating, used a nutdriver to push the rest out. Be careful not to crush the cardboard shell. The wax cools quickly and sets up.
   

I wrapped the new cap with some cardboard to help center, then began potting with hot glue. I started with a thin layer to hold things in place, let cool, then flipped over and repeated. When that set, I finished filling.
   

Here is the finished cap, ready for installation. It is difficult to tell it is not original. You can, however, look in the end and still see it has been replaced if you ever need to prove the point.
   

Notes:

1. Use an old metal pan or something 'cause wax will melt and it stinks. Wife dont like stinky things in her oven Icon_problem
2. Patience. You may have to re-heat a time or two in order to finish. Wax resets quickly.
3. Reccomend not to pot the whole end at once. It takes longer for the glue to set, tends to run and puts more heat on the new cap. Do it in a couple of layers and it works much better. The 1st thin layer cools quickly, the insulates the cap from the big fill.
4. Rebuilding these does take a litte more time, but not a lot, and makes things look more correct.

Tim

With most of those I was able to simply pull the wire by pliers together with the plug, both ends and then pushed the conents out.
Then when I was potting the new cap with hot glue, I used the fact that it melts the external wax on the tube for a long time (the glue keeps the temp for a while) to wipe the wax off as it is often black and dirty. It still leaves enouhg wax on for the paper to be waxy, and it is no longer that important as inside there is a fully sealed new film cap.

If the wires are not pullable just the way it is, 10-15 sec blow with heatgun on low or 5 secs on high do the trick.

I sealed mine up with some of the wife's beeswax. About the right color and melts at low temp. Heated a little up in a small cup on the stove and poured.
Best, Jerry

Here are some brown glue sticks described as 'plasticy.' All else being equal, would you use wax or hot glue?

RE: Philco model 610 rebuild - by Tim P. - gregb - 03-27-2014

I just use the heat gun as morzh talks about and they come right apart and then give the tube a wipe with paper towel and it cleans all the dirty stuff off the tube. I like sealing with the bees wax as it looks more original but the hot glue is more durable. I dont like the look of the regular hot glue and had noticed one time that Micheals Crafts had different colours but when I went back and checked they only have the clear, black, and some purple and pink with sparkles, so I passed.

Thanks for the ideas. This is how we learn things. I'll try a few of those tricks next time around. I figure when the glue ages and gets some dust on it that it'll look about right. I might try the bee's wax once and see how it works. Just need to figure a way to get it into the glue gun Icon_lol . I have a few wax caps laying around I can experiment with.

To be continued...

Unfortunalaly, I am going to have to box this one up with my notes and pics until fall/winter. All my parts came, my time went. Work calls and it will "own" me until fall, so I probably wont get to do much until then.

Thanks for the ideas and help so far.

I don't quite fill mine with hot glue then I reuse the old wax to finish filling them you can tell they have restuffed because the new wire is smaller than the original wire .

This is one of my projects that had an abrupt end ... to be continued. Ok, a couple of years later, a new radio repair bench, some fresh test equipment, I am preparing to restart this restoration. This is next on my list once I get my Amp kit finished, and final calibration on the VTVM. Probably after Christmas. Just warming up the thread. Icon_e_smile

RE: Philco model 610 rebuild - by Tim P. - morzh - 12-22-2016

Well....nostalgic feeling about the times long gone Icon_lol

RE: Philco model 610 rebuild - by Tim P. - TV MAN - 02-13-2017

Alwright - She's on the bench and here we go! Icon_bounce I sure am glad I took notes and have this thread running so I can remember where I am! Icon_razz How time flies!

RE: Philco model 610 rebuild - by Tim P. - TV MAN - 02-24-2017

I finally advanced some on this rebuild.

It is very difficult to pick up a project like this after a couple of years. Icon_e_sad I had to spend some time studying and looking at my notes,, pictures and such. Thank goodness for my notes and digital camera! I am still working on the bakelite blocks. I got the #32 with the 110pf caps rebuilt. I was told earlier that these were paper caps and should be replaced. I also replaced #43, which is also a 110pf cap, and looked just like the ones I dug out of the block. Interruptions have been very bad lately it has been hard to sit for more than 10-15 minutes without someone calling or coming in.
   
   

I need to find some washer/spacers that are bad on this tuner. I could search and spend a bunch of time looking, but I bet someone here can point me to where I can get some of these. Hardware stores don't have much. Help appreciated please.

Look here Tim. There down a ways on the list
http://www.renovatedradios.com/parts.html
Or you might find something at a hardware store. I like the ones I bought from here.

RE: Philco model 610 rebuild - by Tim P. - morzh - 02-24-2017

Look like regular mica caps. Wonder if in other blocks 110pF caps are indeed paper.

RE: Philco model 610 rebuild - by Tim P. - KCMike - 02-24-2017

I had one that was paper but it was so long ago I don't remember what Philco radio it was in.
