I used Black Gate caps when they were available to replace the lytics. Someone told me Jentsen work well. The tubes you're using are good. I'm sure the sound will tighten up if you replace the electrolytics. I use RCA NOS 12 au7 cleartop, mullards are probably better.
Conrad Johnson PV-10A mod experiences?
Has anyone had experience performing a mod on the CJ PV-10A? I'm fond of this preamp, it has that wonderful tube openness and sweetness for harmonics. However over the past 6 months as I've delved into PC audio and DAC improvements, I've come to realize two things about it
1) its slow on transients
2) its dynamically compressed.
I'm using Mullard NOS tubes throughout as these seem wonderfully detailed with excellent base.
Since the preamp is built like an engineering prototype (overbuilt)my gut hunch is that some caps have aged (circa 1993)and need replacement, specifically the white CJ caps
and am thinking about replacing them first with Multicaps.
Wondering if anyone has experience trying to revitalize a PV 10A?
