    I just got a realistic STA-100 on the cheap. Cleaned it, but cannot find the problem as to why it works only in the right channel. If I plug my speaker LL and RR in the speaker set 1, only right will play if I select speaker set 1 output. If I select Rev A output, only left speaker will play...

    Run a single-ended stereo tube amp to a mono speaker?

    Nagaoka for Lp Mono, N-MP1.0--user reports?

    I am really curious about the Nagaoka N-MP1.0--mono (for pre-1967 Lp /45s) -- as the Naga MP series is already somewhat low compliance, (suitable for a heavier-armed mono set-up) and those MP series carts are quite nice, and this mono cart will snap onto any of them-- when I recently noticed...

    Sansui AU-717 and AU-517

    How do you guys go about these amps that lack a 'Mono' switch? Do you just use a mono phono cart for records, but what about mono 8-tracks or cassettes? I still listen to a lot of mono music. What is everyone's consensus on this topic?

    Antique 1950s Stereo!
