My tektronix has packed it (caught fire!) and is not repairable.
If anyone has an old Dual Trace Oscilloscope they want to sell, drop me a line. 20Mhz or up.
Also after a frequency counter and waveform monitor/vectorscope if anyone has them kicking around.
I have a Tektronix 7904 CRO.
From memory it was around 1GHz bandwidth (-3dB points).
It is a 4 trace unit, and has a couple of time units and Amp units.
Spare amp module, ans extender cards for it.
Works really well, and was my main scope until i bought a 4GHz unit at a cheap price. Very clean, and very good condition.
It also comes with a spare frame if you want it, which has a good tube, spare power supply and internals, with bits mising here and there from them both.
