Check out the Hoffman Stout Reverb
18 watts is close enough for R-N-R

Two EL84 is normally called a "18 Watt". 20W-24W is certainly possible by exceeding EL84 ratings. But 30W suggests a four EL84 amp.

lower B+ (~~400V) EL34 would be the ticket. about 30-35W depending on load Z.

EDIT: or a pair of 6V6 pushed to 420V B+ (a la fender deluxe) for 20W.
