Informationen:
                                    The Model 427 is a general purpose oscilloscope employing
advanced, high-quality circuit techniques refined and
cost-reduced through years of development work by EICO.
While low-priced enough for beginners, the Model 427 has all
the control facilities and performance quality demanded in
general laboratory work, production testing, audio and
ultra-sonic development and servicing, ham shacks, and
advanced home workshops. Rugged, simple mechanical
construction, plus clean open circuit layout make this scope
easy to build even by a novice.
1-1 FEATURES
1. Vertical amplifier direct-coupled for minimum phase
distortion, and push-pull for maximum linearity, throughout
(6 stages in 3 push-pull pairs).
2. Choice of direct or capacitive input coupling.
3. One internal bias adjust, and a dc balance adjust on the
panel, for simple adjustment to optimum performance.
4. Four-position (plus CAL) frequency compensated vertical
input attenuator.
5. Saw-tooth (15V p-p, adjustable by HOR GAIN control)
output jack on panel for connection to vertical input jack
when adjusting the frequency compensation trimmers.
6. INTENSITY, FOCUS, and ASTIGMATISM controls on the front
panel.
7. Sharp, clean trace-free of blooming.
8. Instantaneous, drift-free positioning permits centering
any part of a trace expanded to 30cm vertically or 20cm
horizontally.
9. Easy, direct connection to vertical deflection plates
without need of removing and replacing shorting links or
wires. Test leads are simply plugged into rear jacks, and
switch turned from AMPLIFIER to DIRECT PLATES.
10. INTENSITY MODULATION input (2 meg input Z approx. , 20V
ms for blanking beam).
