Stout Reverb question

[JBP]

I'm building  a Stout Reverb as a christmas present. This is my first go at tube reverb and am wondering what would be the appropriate reverb tank for this circuit. I see there are several impedance options. Thanks

Doug has 2- and 3-spring versions in his store. Either will work in that amp.

I personally like the 9AB2C1B (3-spring that Accutronics calls "6-spring" with Medium delay) for reverb.

I second that, second that, second that, second that, second that...
