FWIW... I have found a stash of Y type caps in the 0.047 mfd size commonly used in the AA5 type radio sets. They are priced 33 cents each. I think that is significantly cheaper than some other vendors. There are some other values up to 0.33 mfd but prices vary & I don't think the larger values are as likely to be used in many radio sets. --Wayne WB4OGM
