Need 2 for a EPI 100 rebuild for my father in law. Anyone have a pair that they want to rehome?
Shipping would be to 44039 (Ohio)
Thanks!

Ocasionaly when you do that you may have a small problem as an electrolitic will have
a higher esr than a film cap. At least I saw one famous designer found that when he changed
from an electrolitic to a film cap he had to add a small resistor something in the ramge of
1 to 2 ohmsin line with the new cap .

I could match you 2 bundles of K73-16 or K73-11. They would be exactly on value. Not sure of postage / taxes to USA from UK. PM me if interested.
Likely either 2 or 3 caps in each bundle - soldered together.

Thanks Dan,
Looking for something stateside. I figured I would post here and try for a few days before I hit partsexpress.

Any particular brand you were looking for? I may have some Solen or Dayton around; some higher end pairs as well.
Woody's post got me interested in the change in ESR. I had never considered it or seen it mentioned before.
I tested an NPE, a Dayton, an Mcap Supreme, and a Jantzen Z Cap.
At 1k Hz the NPE was .75 Ohms, the rest were .55. At 10k Hz all were right around .19 Ohms.
Big difference on the low end. At 120 Hz the NPE was 4.64 Ohms with the rest around .83.
Looks like if your cap is in a tweeter section or top of a mid-range the difference should be insignificant.
Take my non scientific, untrained observations with a shovel full of salt 🙂

Actually I’m not picky, they are for my 80 year old father in law. Cheaper is probably better so solen or Dayton would be fine. Pm me how much you’re asking for them please. Shipping would be to 44039.
You might also try this item # on fleabay. 284893168877
I bought a couple different pairs from that seller and all measured within 1% of stated value.
Shipping is reasonable to.

When using a 10uF MKP film cap replacement add 3.3Ω 10W resistor in series to the cap for an EPI 100 to sound best balanced.
