i have a dead tektronix 2221 oscilloscope.
there are several components dead in the power supply
the MTP6N55 MOSFET
Q908 2N2907A
R909 burned (i can just see the first two rings : 39)
CR909 no reference
TL594 IC
R907 0.2ohm
Has someone the schematic, or CR909 reference and R909 value ? |

| I have the same problem. Did you find a solution? Does someone have a repair manual or a schematic of this scope? |
