I had a viking one and didn't have a tuning aid in those days. No one in
my falily understood radio. I had a heck of a time tuning that thing,
every stage had to be tuned as I recall. Ran a pair of 807s and a 4d32
for final as I recall. I did also have the Johnson v f o which was really
stable for its time.
