Sony CPD-300SFT, CPD-300SFT5 Service Manual

Specifications and Main Features

Specification for the picture tube consists of a maximum vertical line protruded measuring about 90 degrees with a circumference measuring 20-inch wide at a 0.30 mm aperture.
It can roughly extrapolate that a measurement in terms of inches estimates to a diagonal image of 15 3/8 by 11 1/2 inches. It translates too, the image size that can be viewed is 388 mm in width, 292 mm in height.
With respect to inches, the viewing image stands roughly at an estimate of 19.1.
In terms of linear maximum resolution, the following calculation can be done: a total of horizontal and vertical grazing equates to a ratio of 1280 to 1024.
The standard area for the image can be approximately calculated utilizing the sine ratio with respect to width and height: the dimensions 14 3/4 x 11 1/8 can be used, then translating roughly to 373 x 280 mm. With other dimension being calculated as 350 x 280 mm.
With regard to deflection frequency, the specified horizontal measures between and includes 30 – 86 kHz, and vertical measures between 48 to 150 Hz.
The required alternating current input for voltage per density is 100 to120 V, 50/60- 1.7A; or 220-240 V 50-60 1.2A currents.
The maximum power output can be translated into getting a maximum output of 150 W.
The approximate dimensions calculated are between 472 x 493.5 x 501 mm which can be further estimated into 18 inches in width with an excess of 5/8 inch, 19 inches in height, 3/4 inch density and 1/4 inch for depth.
The estimated overall mass can be calculated to be 29.5 kilograms on the higher end, 65 on the lower end or 1 ounce.
The incorporation or removal of specific designs and specifications is always up for changes.
