1970's Kenwood KA-7100 DC stereo intergrated amp I purchased new while stationed in Germany 1978. And more recently (last 10 years or so) Technics SA-GX170 intergrated amp Class H+. Both have good preamp for MM turntables and low S/N ratios.
The last amps were, Musical fidelity A250 (as I remember), ARC SP9 and D70, and now LAVARDIN C62 (pre) and AP150 (power). I will stay with Lavardin and maybe commute some day to the mono blocks (MAP). the pre has a MM phono input but I use the Urika in the LP12.
It's odd that the survey heading this thread doesn't allow us to list separate phono preamps. And this is a vinyl forum? I run a Manley 'Steelhead' phono-preamp, Leben line level pre-am and Icon Audio MB845 II 'Special' mono blocks. I confess the MB 845's scare the hell out of me every time I turn them on. Valve power amps always make me nervous but the music makes up for it every time.
