Primaluna Prologue 2 Upgrades

I had a tube pop and glow red so i sent it to mitch singerman at Kevin Deal's recommendation. While he had it i asked if there were any upgrades he would recommend and he suggested replacing the Solen outputs caps with Musicaps. since it was there and apart. Only cost me $100.00

Did it make it sound difference? Seemed a little smoother but not a huge change.

more change with tube rolling

Not parts, but I rolled tubes and the improvements were fantastic. I used all NOS made in UK around 50's Mullards / Brimars in pre and driver sections plus UK made NOS GEC KT88.
The tonality of amp become miles ahead from stock tubes, its like day and night, thats all I can say.

Replace the original KT-88 power tubes with KT-120's if you do nothing else. You will get significant improvement in bass and detail. Prima Luna OK'd the 120's use in all their amps at the beginning of 2013
