Trafo for reverb 14k o 22k on primary?

[sergio]

I don't know what is the right impedance for it.

I use a reverb circuit with 1tube.

In this site , where I make order there are two type of trafo for reverb:

1st: 3,5w prim:14,5K sec:4ohm 12,50Euro
2nd: 3,5w prim:22k sec:8 ohm (hammond) 18,30Euro

what type choose?
Thanks
