Make sure that your replacement finals are 6146, or 6146A's, never
B's!
I've got to challenge this statement. This rumor has been circulating for
several years now. When I received my new HW-100 from Heathkit in 1968, it
came with RCA 6146B's. There was a note enclosed that said that they(Heath)
were having problems getting 6146A's and that the 6146B's would work fine.
They did. The radio neutralized without any problems and stayed that way.
I had the radio for about 10 years and when I sold it, it had the same
tubes and still produced full output.
