What is the sensitivity of your speakers ?
rated 93db ... the other pair rated at 96db
Hi sir Teta,Very interesting upgrade there. Do you think it (OP amp) will also work/fit with the original poster's item (FX Audio Tube-01)?And where do you source the said OP amps? Thanks!
Where to get upgrade tubes for these? I'll purchase one soon.
please post pictures, what preamp is that?, the 6j1 did not use op amp afaik...what psu are you using? it should be 12vac at least...
this amp can be hacked for lower gains....if desired...just two resistors in parallel with the plate load resistors.....R15/R20, just solder in 4.7k metal film resistors to the existing ones, or replace them with 2.7k resistors lowers the gain of this line amp..
Can i remove some resistors to increase the gain?😁
ecaps drying out can be culprit...
My FX Audio Mini 6j1 tube preamp is now two year old. Lately i noticed popping sound is outputted by the preamp to the amplifier, ano po kaya ang dahilan?
na try mo na ba i-pull out the tubes and re insert baka me maluwag lang o dumi sa fitment between tube pins and tube socket
agree with tony about the caps but 2 years is a not really a long time imo so i think potentiometer/vol knob might also need replacing
onsidering the quality of china goods, that is not surprising...
