The Tektronix Type 82 is a dual-trace plug-in for the 585 and 585A oscilloscopes. The Type 82 combined with a 585 or 585A provides a 4 nanosecond risetime. The front end of the Type 82 is a 7586 nuvistor cathode-follower, followed by bipolar diff-amps and diode channel switching, followed by a distributed output amplifier made of three 6DJ8 tubes, with differential 93-ohm outputs. The use of a distributed amplifier in a plug-in is unusual. Note that the 58x series differs from other 500-series scopes mainly in the fact the vertical signal interface between the plug-in and the mainframe is a low controlled impedance (93 ohms), as opposed to other 500-series scopes that present a high impedance to the plug-in.
