Question:
Is documentation available to explain the amplifier changes necessary when
replacing 3DREP 6-1X; 4WRZ series 3X thru 6X; 4WRA series 1X with the
current series valves, 3DREP-2X; 4WRZ-7X and 4WRA-2X?

Answer:
Yes. The current series Euro-card format amplifiers for these valves are:
R901002090   VT-VSPA2-1-2X/V0/T1 - 1 ramp time, or
R901002095 VT-VSPA2-1-2X/V0/T5 - 5 ramp times

Either version uses our 48-pin cardholder R900020154 VT3002-1-2X/48F

Please review the attachments for further details, diagrams and technical
specifications regarding analog amplifier, VT-VSPA2-1-2X/V0/T**
