[R-390] RF Rack Slug

[DW Holtman]

Good Morning,

I'm looking for an RF Rack slug, I have a broken one on my Fair Radio Blue Stripper.

I have an IF slugs that I would could trade. I was not sure if the RF and IF slugs were different. I removed an RF transformer from the RF Deck and hooked the coil up to a digital LRC bridge. I measured the coil with no slug and it measured 64 uH. Next, I insurted a slug from an RF rack into the form, it read 602 uH. Last, put in the spare that I have it read 246 uH. I tried this with several RF and If slugs, they all read the same. The permability if the RF and If slugs is a lot different. I'm sure most of the old 390A hands already know this. 

If anyone has one for sale or trade, please let me know.
