Ordering from Justradios.com
 
Hello is it safe to order capacitors from Justradios.com? And is it true that miec capacitors are good?

Plenty safe as far as malware/tracking is concerned I was surprised to find it had no trackers ,highly unusual , usually most websites have at least Google in various forms.


As far as quality it looks high to me --not the highest but its pretty good .


Mica capacitors were much used in old tube radios in the RF section for high stability ,the modern dipped ones are reliable.


Don't like polyester though stick to polypropylene .


If you are thinking along mica lines for audio then go for LOW values of COG Ceramic approved by several of the big audio design engineers and approved by D.Self.

I have ordered caps and resistors a dozen times or so over the years (for antique radio repairs among other uses). I have never had a problem with an order or parts quality.

No i meant miec electrolytic capacitors.

In my opinion, the most reliable electrolytic capacitors are Nichicon, Panasonic, and United Chemi-Con. I don't use anything else. Stay away from Illinois caps--those are unreliable.

Yes but
 
Miec are the only ones who sell electrolytic capacitors that are rated at low uf and high voltage like 33 uf 450v.

I used some MIEC 600v rated caps in Dynaco restoration once as the first cap after the rectifier. They leaked after a few months.

Not true. All the major manufacturers sell caps rated at 450v in standard values such as 10uf, 22uf, 33uf, 47uf, etc.

I usually order from Digi-Key because they offer free shipping if you order via regular mail (not online) and pay using either personal check or money order. This only applies to orders from the US and Canada.

This can result in significant savings, especially if you only need to order a few parts and it really doesn't slow down the ordering process much at all.

Most people are not aware of this since it's somewhat hidden under "Terms and Conditions" in the fine print at the bottom of their website. When you send in an order it's a good idea to mention the specific section.

Here's what it says:
