Replacing Axial Electrolytics with Radials

[ncusack]

Just wondering if anyone has a visual example of using radial caps in place of axials. I currently have a HotRod Deluxe in need of new power rail caps. I have radials on hand but im not sure of the best way to fit them where the axial caps were.

I wouldn't be looking to install radial caps in an existing amp that used axial caps.  You're almost certain to have problems getting the leads to reach the wide spacing the axial covered, and then you have to worry about how the leads will be strained over time.

as to "new" construction, i used radials once, went back to axial's

Only reason for using the radials would be time. It would be 2 weeks possibly more given shipping issues these days before I could get the F&T caps I would normally use. What if I layed the radial on its side and bent one lead up around the body and tacked on a little wire extension, wrapped that all in shrink wrap and siliconed it to the board like the axials? Sound reasonable?

No problem using axial.

Con : I would like keep amps looking as original.

I bet Hoffman would be faster.

Id imagine Hoffman would be the only source id use if I weren't in Canada. Tanks to Doug for hosting this forum though though. It has been a great resource over the years.

I live in Canada too. Do you look at NexGen , Ottawa area ? You can pickup parts

Postage/ order over the border is very very slow.

Yeah I'm out on the east coast and everything I've had ship from Ontario has been backlogged lately. I will be ordering things regardless but this is why im curious if anyone has MacGyvered radial caps into an axial slot before.

A radial cap are same, what different with MacGyvered ?

Are you aware of Just Radios in eastern Canada? Ahhh  but I see he isn't allowing pickups.   shame.   He is in Ontario.

MacGyvered is not a brand or type of cap although MacGyver certainly could have built one with a tube of toothpaste. 

MacGyver was an old tv show about a guy that was handy with common household items. He later showed up in the Stargate tv series as the smart-alleck team leader.

I recently took these out of a Super Reverb...  you can see what HPB is talking about that the leads are too short so you have to lengthen them. Doing this is just tacky and should only be done in an emergency.
IMHO.

Thank's, It is first time I heard them.

Just Radio wrote ;
" We are operating on a mail order basis only.  Sorry but NO pickups of capacitor or resistor orders.."


My question; If mail order basis only, why they wrote  :" NO pickups of capacitor or resistor orders." ?
Can we pickups bigger parts like transformer, speaker ?

if vertically mounting, drill holes in the turret board so that the cap body is mounted on the board. connect the leads under the board. not recommended to suspend a radial cap by the leads alone.

horizontal mounting radial cap is simpler: connect the leads to turrets - for larger caps secure the cap body the board with a wire tie looped through holes in the turret board.

mounting radials vertically is typically best practice.

If I can suggest

Simply bend the positive terminal (it is longer) of the cap to the opposite side of the capacitor (look here)



If the terminals are too short to arrive to the turrets or eyelet, there is a bit more work to be done

First use a piece of solid core wire to enlenght the positive terminal (with a tin solder), put on the elongated terminal and on the cap a piece of shrink tube as to prevent that the terminal move

I hope I've explained it in an understandable way

Apart from the ugly result there is no harm in that. Dont forget to shrinkhose the entire extended wire so it don't touch the body of the cap. Done that a few times myself to test stuff. In the meanwhile you can order the proper axial ones and swap the caps when you have them sent over. I wouldn't wrap the entire cap either. There is no way you can determine the value afterwards... maybe a tie-wrap  but that's it.

Five minute job

Radial to Axial

this is how it can be done





as you can see values are easily readable despite all is covered with shrinking tube

Note that I bended to the back the positive terminal, if you bend the negative terminal writes will be 100% free and more readable

I do something like the above almost every week on pinball circuit boards that use a value of electrolytic that's no longer available in an axial version--without spending $15 for a $2 part at least. I zip tie mine down instead of shrinking since the originals were tied down and holes are present for that.
