I'll be building something truly fun... just received the Hashimoto output transformer in the mail for it. :)
A little mono amplifier with built in phono stage. Shortest signal path possible, as little amplification as absolutely needed, no volume control, and single 71A output tube for glorious 0.7W output for late night listening of mono records.
With full EQ control, both turnover and cut in fine steps....
Can't wait to get started on it, but it will probably drag out well into the winter without any quality time available to build..
