Russian caps of interest

[phase]

Polystyrene are all foil.

1uF styrene???

You can get Russians to 1uF, and MultiCaps to 3uF.

A 200 v, 1.0 uF RTX is right in line at 1.20 x 1.80 so these may be legit after all.

I have been using the 4.7uf K71-4 as my tweeter cap and I prefer them to the 4.7uf K75-10 they replaced.

 

[wolf_teeth]

Where did you source K71-4 that large?

1x K71-4V 4.7 UF 160V 2% Capacitors, polystyrene, metallized, compacted. USSR | eBay

My polystyrene capacitor: 0.1 uF, 630 V, L=55mm, D=25mm

I have also seen 3.9uf and 10uf on eBay

When I was looking before, it seemed the 1uF was the largest I could find. I managed to find a pair of MGBO metal-canned 4uF 'styrenes and I quickly nabbed them.

Thanks for the good info!

I was looking at MGBO 1.5uf. Have you listened to your 4uf?

 

[wolf_teeth]

I have not yet, as I've only had them a couple weeks. I haven't even tried to fit them in a design yet. So many people swear by 'styrenes, that when I found them that big I jumped. I will be getting some 10uF as well.

Couple days ago there were 4x of the 10uF left. I went to order today, and only 2x were left.
I ordered a quad of the 4.7uF, and apparently the last 2x of the 10uF.

So heads up- the 10uF are now gone from bergtrans. I have not found them anywhere else online, and I have looked!

Later,
Wolf

 

[Zedguy]

His listing still says 10 of the 10uf available.

 

[wolf_teeth]

Then he updated the listing. It would not let me order more than 2 before.
I guess I'll get 2 more then....

I bought 4x Russian 4.7uf 125V Teflon caps many years ago - never used them, as each one is larger than a can of beer.

Are you speaking of the brown rectangular box type ? If so I've tested a couple of them.

 

[Zedguy]

Yes the rectangular type.

 

[Zedguy]

I have been looking for a pair of these.

[Zedguy]

Also I was incorrect earlier the polystyrene are MPGO not MGBO.

Yes the rectangular type.
