I have to say, 46 y/o and it outperforms every one of my new Yamaha digital amps. Clear sound, crisp across the range, excellent base, I wish they still made them like this instead of what is out there.

Mine is old ( what do you know) But seems internally in perfect tuning. Warm one buddies. Had nothing to do with the switches , which is pretty impressive for it's 46 years old. Change the fuse lamp for LED. I did exchange my 90's harman/kardon for that unit and I regret nothing. Heavily built. Double knobs to fxxk you up, or does it? :) Great cheap amp. My 76's Kenwood's needed much more attention, but that's still relative.

This sinto has a fine sound, solid and deep bass and a very richer sound. One of the best sinto I never heard.



re: STR-6055

I got one piece with not working tuner. Power apmlifier had worked okay.
Thank Adagio62 for manual, I discovered burned R804 in the 15V voltage stabiliser in Power Supply section. It is necessary to use at least 1/4W resistor, better more, because of its high power load. I wonder they used just low power resistor in the original.

I have been surprised by clear sound, a sensitive radio tuner and low distortion.

To Kahuna5's question :
The version I have has also 5 fuses. It is an iternational version (for 110-240V). Just one fuse is on the transformer's primary circuit, other fuses are for some internal voltages.


re: STR-6055

Service manual mentions a GEP and a NEP version - What's the difference? How would one know which they have?

re: STR-6055

The codes denote regional differences, usually to the power supply. A quick glance at the service manual shows five internal fuses in the NEP model (Japan?) and just one in the GEP (General Export?).
