Interstage Transformers

  • Interstage transformers can be made in different ratios, primary currents and voltage ratings.
  • All designs will exceed -1db 25Hz to 20 kHz.
Primary CurrentRatio UsePrice
20ma.SE INTERSTAGE$118.00
20ma.SE TO P-P GRIDS$148.00
35ma.SE INTERSTAGE$134.00
35ma.SE TO P-P GRIDS$169.00
50ma.SE INTERSTAGE$150.00
50ma.SE TO P-P GRIDS$188.00
70ma.SE INTERSTAGE$221.00
70ma.SE TO P-P GRIDS$277.00

IMPEDANCE RANGE ON PRIMARY CAN BE ANY ONE CHOICE WITHIN 1K TO 20K
SECONDARY IMPEDANCE WILL BE SAME ON SE INTERSTAGES
SECONDARY IMPEDANCE OF P-P GRIDS WILL BE SAME AS PRIMARY BUT CENTER TAPPED

The secondary of a p-p grid interstage, in order to maintain a wide bandwidth, must be same as primary. Having both sides of secondary same as primary Z will cause dis-coupling and phase shift and bandwidth will be compromised. Gain of driver will maintain drive level.
