I’d change the preamp tube (V1) to a 12AY7 and try a 6V6 power tube to start with. I need to think on other circuit mods…..

A 15″ speaker will work as well other sizes with the 2 Stroke. Just as with a guitar, the output and tone will vary with the speaker’s voicing and efficiency. I bet a Eminence 12″ Cannabis-Rex would be a good harp speaker.
