The Apetite was a 13 watt integrated discontinued about 2-3 years ago. Was about $4000-5000 then.
I wrote to several people who had it. They said:
The Apetite doesn't have the
harmonic complexity of the upper models but is really excellent.
4 pieces of small 6072 as preamp and driver tubes,and 4 pieces of CV-428 ( on tubes noted 256M made in England ).The E80CC's can be found in various tube shops and generally sell for $50 each and their are two. The CV428 can be had from Parts Connection at $10 each. The CV428 is not common but inexpensive when
found. All these tubes should last many years since Shindo runs his circuits conservatively.
I really enjoyed the Apetite, it's very energetic and lively with incredible punch and articulation.
Hope this helps
