[Drake] TR7 bulbs

[HENRY PFIZENMAYER]

Just had the PTO light bulb burn out in my TR7 ... looking at Radio Shack
... it says NR 53 bulbs are only good for 30 hours at 14.4 volts.. now I
know the exponent for longer life is huge but from 14.4 to 13.6 or so is not
much change ... are the 53 bulbs "normal " or did Drake get a special ?
While I am at it , anynone have the specs on the little wire leaded bulbs
used elsewhere ??? All I have is the Drake part number in the service manual
..

Finally is everyone getting two copies of every message ? or do I have a
problem ?
