Great playing radio, unable to find my notes on the one that plays in my work shop. First and only set I have worked on with a 17EW8. If I remember correctly it is used in place of a 12AT7. In reading some were about using the 17EW8 was due to increase in line voltages. I purchased several to use in place of 12AT7. At the time they were cheaper. I did replace the original tube in my set big improvement on both AM&FM. Something about a 3or4 section E Cap? Using a 1N4007, sorry about not being more helpful.
