Lots of good info already post. Parts are not that expensive so have at it. If it was me, I would use the V-Cap ODAM as my first choice and see if that floats your boat. We use them exclusively in our designs. We have also use the copper Milflex with good results. One of the best comments above is space. Be sure to look at the size specs first to make sure things fit in. Audio Note and Nichicon capacitors are excellent and so are the non-magnetic Audio Note resistors. Things get a little pricey but if you doing the labor that is a cost savings there. Last especially for tube equipment, look for AC filter chokes and other chokes to replace capacitors, etc. All parts have sound but to me, chokes are a big benefit plus a lot cheap!
Happy Listening.
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!
