About the defect: The defect is not because the "burn-in". I related the "burn-in" to sound quality. Believe me, the sound changed after some days. I had been comparing (plugging and unppluging the headphone in either gears!) both gears. I was disapointed with the V3 but yestarday I felt the changing! Exciting!
The defect happens only when I make tube rolling. I tested 3 differents tubes. My tubes are in good conditions.I used them on my phono preamp, because it used 12AU7 tubes alsol.
About the supposed crosstalkig: The distortion is very high in a channel only! Quite possible any person to feel it! One of the tubes (RCA) simply won't work, no sound at all! Electro Harmonix works with very high distortion on the left channel.
About mods: And yes, I will try saome mods and I would like so much to try the mosfet mod. Nice your suggestions about power supply mod! I liked it!
By the way, IRL510 is veru diffucult to find here in Brazil. IRF510 is easier. What about this (IRF510)?
Thank you! Your message was helpful!
The IRL510 is the best replacement for this amp. NOT IRF!
Make sure you are using only compatible tubes such as 6922/6DJ8 or equivalent. You mentioned 12AU7 in your post...this is NOT a compatible tube for the Bravo V3!
