Help!!! I want to use my music fidelity A1 amp 20w/ch 8ohms speaker load as a headphone amp (HD590's) Can anyone tell me the correct way to do this without blowing up either amp or headphones?? Most eligant solution will be rewarded with a 'thankyou'
hi,
usually it´s done with a series resistor but i don´t know how to calculate that exactly.(in a grundig amp it was 560ohms/1W)
but that´s definitely not a high-end solution.
for a better sound better build something with a good opamp(opa134...)
i wanna add a headphone jack in the same way
so i´d appreciate a hint for calculating the correct value for the resistor
