Title: Heathkit HP-23, Millen Coils, and 813 Tube Post by: Jim/WA2MER on April 24, 2018, 07:45:37 PM Looking for a Heathkit HP-23 or HP-23A power supply, an 813 tube (American made NOS or excellent used), and a set of 80 Meter coils for my Millen 90800 exciter.

The Millen part number for the coils, which is usually stamped on the ceramic bar, is 43082. Need two of them. If I don't find the coils, I'll settle for the ceramic plug that the Millen coils were built on and I will wind my own. See the photo for what it looks like. The pins are spaced 1/2" apart. I need a plug with only four pins like the one in the photo, but a five pin plug will do as well. I'm going to NEAR-Fest, so I'd prefer to find my stuff up there in order to avoid shipping. 73, Jim |
