Built like a tank - solid ES quality. Sounds great.

A stout amp from the mid 80's with basic settings, but very reliable and excellent sound quality.



re: TA-F555ES

Just brought home a used one. Hooked it up to my tester system which is comprised of cheap speakers, tape deck, and other equipment that if something bad happens, I'm ok and my other system is free from harm. I powered up the system. Zzzzzzzzzzzzzz pop! Smoke came rising up from the top rear left of the Sony TA-F555ES.

re: TA-F555ES

Update: It went into protection mode. I took it to a technician for repair. It's back. 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 like it.

re: TA-F555ES

Update: one side only is heard through the speakers. I swapped in a Concept 6.5 a while ago. Now I can't remember which side stopped working on the Sony. I will say the Sony and cds go together like peanut butter & jelly.

re: TA-F555ES

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 :)

re: TA-F555ES

I agree. The caps are in a strange spot. And they just barely touch the top cover. Ouch!! If something ever falls on it. But the TA-F555ES does sound good.
