I have a few radios that require the 6U5 eye tube. In a couple of the radios I can use a 6E5 ,
,BUT it almost stays closed with very little movement. I tried a dim 6U5 and it opens and closes much better.
If I was to try get them from the United States ,,the price is outrageous with the dollar exchange and the shipping.
I am hoping someone here in Canada will have a couple for sale.
Thanks
