$45 is obviously a rip off for that relay. Since Ameritron makes a big deal about selling any individual part Id start there to get a more realistic resale price. To find the source go to your local
Comments interspersed.. I don't think $45 is the actual each price Jay sells them for. However, it could well be a realistic cost for him to put one relay in a box and ship it. Might be that 3 relays
Yes, it is. I've bought several. And, you can find them on his pricing / ordering page at $45 each in quantities of 1 to 9. http://www.arraysolutions.com/pricelist.htm - search for the text "10kw rf
Both the RCS-8V and the Ratpak use an indentical looking relay with the same part number on them. It's possible that they are a standard part that has been customized differently for the companies,
