Tektronix readout repair. I have a problem with the Tektronix rd Readout is not working. Displays only the spot, no time base on the screen , from time to time, jump to the next position where it should be readout.
After adjustment knob charcter scan, there's a readout, but the characters were, or blurred, or not drawn to the end - in pieces, imposed on themselves. The readout is off everything works. For all kinds of advice I would be very grateful. Similar manuals:.

The input amplifier contains a JFET source-follower buffer that uses a 2NA Tektronix part number biased with a drain current of The input amplifier drives a Tek-made differential amplifier chip, part number The original instrument design utilized an all-discrete switching power supply, making this an incredibly light portable scope.
Unfortunately, this power supply was extremely difficult to troubleshoot when it went belly-up. At serial number B and later, the design of the supply was simplified to use the same basic circuitry as found in the A using a Tek-manufactured controller chip.
In general, the is a nice-looking, easy-to-use oscilloscope. However, the was probably one of the worst mechanical scope designs to come out of Beaverton engineering. This was the model that caused bench technicians to think that the factory should send all new mechanical engineers out into the field to work at a Service Center for a year to get an idea of good and bad mechanical designs.
First of all, the design departed from the proven steel PCB mounting screws. Instead, it uses brass screws in a design that requires a screw-holding driver to get the fasteners in place. Brass screws are non-magnetic and getting them started in some of the more obscure places on the vertical preamp board is extremely difficult. Since these scopes are of an age that one can make modifications without incurring the wrath of Tektronix technicians, it is suggested that these brass screws be replaced with steel screws, preferably ones with captive washers like the original brass screws.
Most dedicated Tektronix fans and ex-technicians do not like changing any circuit design from the original, but some mechanical changes such as this are for everyone's benefit and don't affect operation of the oscilloscope in the least.
In fact, if the circuit boards are removed, the original threaded holes in the castings can be drilled out and retapped for screws.
