very nice sound

yes, now it's works. no more getting too hot. very nice sound with 2sc2922. i loved it.

i didn't change anythings at all. i found c18 was wrong number now i just corrected it, thats all. thanks lots.


i found 2sc2922 sound quality is more btr then 2sc5200.

thank you.

vlu wrong

hi, the vlu was 4.7nf but it should b 47nf

now the question is, power supply should b 36v. my transformer is 56 volt dc. it functioning well..no abnml heat at all. do you think 56v should b ok or should go down to 36v? i am not good in electronics.

thank you.
