Update: It went into protection mode. I took it to a technician for repair. I've been using it for the past year. It's hooked up to a Sony st-s500es tuner, tape decks, turntable, CD players, and 6 speakers selector box going to various speakers (Altec 14, Valkyrie, ES200 with dps10 sub, Advent A4).

The speaker ohm selector switch is located on the back. First impression: Relay takes awhile to click, plays loud, detailed, clear, and highs/mids/lows are amazing thanks to its 5Hz-200kHz and damping factor which make some of my speakers smile. Jungle and grindcore play well.
The 'bass boost' seems more like a nudge than a boost! Tone controls seem bland or weak. I connected a EQ to help, it did. The unit does run warm and close to egg fry hot.
I placed a Elan cooling fan on top. Sound profile: This does have a distinct Sony sound. Performance wise I'd like to compare it to a G-7700 but I won't. Compared to an str-7065A, I think it sounds a bit better overall. I'm still learning.I have not taken the volume past 12 o'clock.yet. I want to keep my hearing.I agree the caps are not in the best location. The whole unit is almost as heavy as my Dodge.
I hate to giggle but I'm in the process of trying to fix one right now.which is what brought me to read your comment (and grab a schematic).It would be a whole lot easier to repair if they hadn't mounted the filter caps directly above the output stage secured with 2' long wires.:(Yeah I know the filters have to be on a short leash but maybe they could have mounted them under the preamp or somewhere that doesn't need to be serviced as often.I will prevail - but it's taking longer than it should have:).
The topper, like a few other early ES units, was not released outside its country of origin so, elsewhere (everywhere), the F555ES represented the top of the newly (re)launched series.A fairly basic amp if very healthy indeed, and quite a best-seller, too, but the ES line was (re-)starting afresh so the PPS, Heat-Pipe and other old/new/old technologies were banished.The one reminiscence is the placement of the volume knob: left, just like the and preamps, thus hinting that these amps also used the 'simple signal path' inaugurated with the in 1976.
