RE-Capping Sansui's

CDFixer

Number 1 USC Trojan Fan
There has been a lot of talk about recapping the receivers so I thought I would post some pictures of how I use the Panasonic Snap-In caps in the power supply. This mostly applies to the 8080/9090 and there DB brothers.

1. I clip the two extra connectors off the caps.

2. I then crimp uninsulated ring terminals (18-22 guage #8 Screw size) to the capacitor. I crimp rether than solder as I think this is a better connection especally since you will be soldering to the ring terminal.

3. Then for the 9090/9090DB series I use a 1 1/4 in diameter flex coupleing that I get at Lowes or Home Depot (Plumbing dept). This coupleing is about three inches long and has hose clamps at each end, I remove the hose clamps and cut the coupleing just past the hose clamp indention. This will then slide over the cap and will exactly fit the 9090/9090DB clamps. The 8080's don't need this as these caps are the same diameter as the orginals.

4. Mount the caps and the ring terminals make it easy ot solder the wires in place.

Here are some pictures

On same way I have installed main caps for G8000 (I used Panasonic 8200uF/80V, (8 pieces), but now I dont have picture to show you how it looks like.

Here you can see how I have made new main caps for G7000. :smoke:

Regards!

That’s some fine work guys. Thanks for the info.
Thank you Tom for help with buying these “hard to find” 6800uF/63V capacitors! :thmbsp:

Problem is that you must use capacitors which diameter is max. 2.5cm.
For yours information, you can use two types capacitors from DigiKey:
- Digi-Key Part No.493-1135-ND Nichicon
- Digi-Key Part No.565-2695-ND U.Chemi Con

This thread is from 2006.. you might get a response.. but I doubt it. Learning form experience, the main filter caps will hold a charge for a couple days..i can totally understand your concern
 
Clip a 1K 2watt resistor across the terminals of the caps for about 10 secs that should discharge the caps. I believe that the 9090 has bleeder resistors across the caps ( I know the DB models do). They will discharge the caps in 1 to 2 minutes.
 
I believe I recently read a response from echowars that suggested a 25 watt lightbulb with leads and clips soldered to it. Sounds like a good idea.
 
Aw, just put your tongue across the terminals. It'll both discharge it and tell you if the cap is good.

The AU-999 I'm working on sat a full 24 hours and still had PLENTY of power left in the caps..so leaving them sit probably isn't the best option. Of course it doesn't apply to all units.

Food for thought....
 
Safety first. Maybe I should have added you need to be a trained professional on a closed track to check caps this way.

I once put my tongue across a +90V "B" battery. For you young guys we used to power tube equipment with batteries and the "B" Batteries were used for the B+. Needless to say I didn't do it again
