Tektronix Type 503 Oscilloscope
“This is our entry level model”
Delighted with the response I got to an earlier installment on Lazarusing a Tek 564 ‘scope I now tackle an older but lighter one, the 503. Junior and modest as it may look compared to its bigger brothers in the 500 series, the 503 has enough tech content to amuse and educate.
