[R-390] Dial Lamps

[Roy Morgan]

  Here is a bit more info from my files:


  MicroLamp  <http://www.microlamp.com/> lists the following 328 series bulbs:
Unfortunately, there's no prices nor are there any specs save the bulb
type - T13/4, volts - 6.0 and amps - .20.   I cannot find any listings on 
their web site today. You are invited to email them.. (click the light bulb 
if you see one.. gawd their site is useless!)

Here are variants of the lamps in the R-390 A

In the past Al Solway <beral@videotron.ca> has offered some 328's for sale, 
I don't know if he has any left.
