Has anyone tried the Kustom defender? Comes in 15 watts for under 300.
I've seen 5 watt version on Thomann, it's 5 watt class-A so it's probably not far soundwise from other mentioned amps in the 5 watt region, but the downside is Kustom does not provide schematics for this model, and there's no space in it for bigger tubes (like EL34 or 6L6, which both are reported to work with say Special 6).
15 watt version seems more interesting, still no schematics no big modding community like in Valve Junior / VHT case.
