Tektronix 503 differential x-y oscilloscope 3502

Tektronix 503 differential x-y oscilloscope 3502

This 5 inch oscilloscope has been completely refurbished both mechanically and electronically. I have installed a new P31 ceramic CRT. All Sprague Black Beauty capacitors have been replaced. Tubes have been all tested and any suspect replaced.It has received a full calibration and a 72 hour burn-in test. See picture, the cart is not included.
This oscilloscope is suitable for a wide variety of applications, including audio distortion testing, amateur radio modulation testing, power supply tests, and low-speed computer work. It features the same triggered sweep that the larger Tektronix labroratory oscilloscopes. The x-y feature allow frequency comparisons and phase testing of amplifiers.
Sensitivity: Calibrated 1 mv/cm to 20 V/cm.
Sweep magnification: X2, X5, X10, X50
Included Accessories: Tektronix cd manual
