completely false statement. Been repairing amps for so long now it comes down more tot the quality of the parts then the heat if the units are vented correctly and they have good heat dispersion. Any old component you purchase probably needs a parts upgrade. Last night we compared three class A amps Coda, Carin and BEL. We were surprised with how well the BEL amp sounded. Very musical sounding amp built in the 90s. Still going strong although I think changing a few caps is a good idea, I also think the Nichicon PS caps will sound better along with Audio Note resistors and capacitors or Amtrans.
I have been repairing, modifying and building audio components for close to 30 years now. Don't worry to much as the caps, etc., can be easily changed.
