Reverb...gotta have it.

  This is in the interest of tank reverberation circuits.
  Old style Reverb is really cool, I think if I get it up and running it might be able to continue to provide a great service/performance.
  Valve Jr. 'sparks' it up, but I need to match the impedance of it's output to the transducer..then I can worry about the recovery and mixing!
  I figured the old [about 1 easy year] digital echo had to go, I cabled around it, yupp, it has to be gone !
  That leaves a big hole in my time delayed effects plans.
  Searching for DIY tube reverb for the last year+ really doesn't bring much of use except the Fender 6g15..fine design.
  ...And the basis of the "Jr. Reverb" approach...using a Valve Jr. to drive the reverb input [looking at the two schematics, there are numerous similarities, and two glaring differences.
  1 the Fender design has 1 more triode.
  2 that makes the valve Jr. more difficult to use as the full reverb circuit [1 triode shy of having recovery/mixing].
  My clone has that tube socket and heater supply etc. in it.
IIUC...the EL84 5200ohm output needs about a 12:1 ratio impedance [that'd make it 433ohms, not bad] to drive the input transducer [490ohms], that means a 3:1 voltage ratio transformer [also turns ratio], math check.  
  Would a power transformer be a viable option for this?
