SONY TA F808ES

Hello there,

I have a Sony Ta 808es amp which my dad gave to me, I recently checked transistors of amp which located at the bottom. There are 8 main transistors, 4 of the are SONY brand (with S logo), the other 4 are Toshiba brand ( with T logo). Amp plays perfectly good, no buzzing or any distortion or any defects in sound. Should I really concern about the transistors, do they really effect any how. Cause one of my friend just insists it effects, and that bothers me..

Thank You
Niko

TA-F808ES uses both S & T type mosfets, so i believe the unit is still in factory state. Do not change unless you have the confirmation that amp was serviced and mosfets were changed. If in doubt check following site:  https://audio-heritage.jp/SONY-ESPRIT/amp/ta-f555esj.html
In Japan it was sold under F555ES name.
