[R-390] Hello

[Mike Wells]

I am new to the list. I just picked up a couple R-390A's last week and
thought I would see what sort of helpful pointers I could get. The receivers
I picked up are nice units. One is a Collins built unit and the other is a
Capehart unit.

I'm sure that there has been lots of chatter about the 26Z5 rectifier tubes.
I am in need of one and started looking around and it appears they may be
hard to find and expensive. Is there a good source for them?

I am also curious about the calibration of the carrier level meter. I have
adjusted the zero set point, however with the two 390's setting side by side
one registers a much higher reading on the same signal, yet they both hear
very well. Guess that only listening by ear isn't a good sample so would you
think its just an alignment problem?

Thanks
