Not a kit, but like the Akitika, a lm3886 design:

I finished mine a month ago. Akitika was my first choice but shipping and taxes made it too expensive for me at the time. I'm very happy with it, but you will have to buy all parts yourself, including the case. Documentation is very good, I had no problems building it. Getting and selecting parts was very time-consuming though.
Am looking at the Akitika pre-amp now... need a new project šŸ˜€

I do not mean to sound rude, but the 300B used in the TU-8600 was obsolete before WWII ... IMHO and for a fraction of the cost, I would buy a current Dynaco kit with the improvements made by the people now selling them.
Time proven design, components easy to get, very good sound and easy to build... There is even an sca35 clone available which is an integrated preamp and amp.
Before you "dis" something you should get your facts straight.
FYI:
That "obsolete" tube is still in production from several manufacturers. It's very popular with the SET, high efficiency and open baffle speakers crowd. If you do a Google search for 300B amplifiers you'll get a lot of 300B amplifiers in current production. Some of the prices approach 5 figures for a single monoblock.

There are other low powered triodes that are "obsolete" and still relatively popular. They include the 2A3, 45M and 845. New production versions of these tubes are also available.
