Lots of great recommendations and suggestions on upgrading. I for one really believe in it. I went from Janzens to Duelund copper CAST coupling capacitors in my tube-preamp and at first, I thought not such a good upgrade, but after ~100-hours of break-in, wow... Increased inner detail and for lack of a better term, body in the music. My good friend has a pair of Welborne 300-B SET's that we're going to do a component upgrade to sometime next year. They sound surprisingly great for their cost and what they are. Simple circuit and all... I believe they will sound notably better with these upgrades. As many have said, please don't judge the switch until you've given some time for break-in !
Question About Capacitor Upgrade in Tube Amp
Hi,
I am preparing to do a coupling capacitor upgrade on a recently purchased tube integrated amp. The two 0.22uF on the preamp tubes are fairly straight forward. But I noticed another similar model 0.33uF cap on the large filter capacitor for the B+ supply that is installed across the hot lead to ground.
Does this cap on the B+ just block high frequency noise from the power supply or does it have any effect on the amp tone? Is there any reason to "upgrade" this cap?
I know it may be hard to tell exactly what is going on without a schematic.
Also any recommendations on a good cap to use in the upgrade of the coupling caps? I was looking at Mundorf SilverGoldOil for the quality at not too crazy a price. The amp already sounds good but lacks a little clarity that I think a coupling cap swap will help with. It is SET 300B amp.
Thank you!
