@tablejockey , So I ordered two (2) .22uF V-Cap CuTF Series capacitors. They are copper foil and fluoropolymer film.
I removed the two small caps on the two center gain tubes (the center, innermost two preamp tubes). The layout on the HP integrated is clean but it’s totally stuffed into the chassis. This was a 30 minute project because I had to move slowly working in tight quarters.
I would like to swap the caps linked on each of the power tube sockets. However, they left very, very little room to do so in the HP integrated. The stock DuRoche caps are quite small --likely .5" diameter by 1" long. I cannot seem to find many options that will fit in these spots. I’m down to Audience Auricap XO, maybe Audio Note (they are all sold out) or maybe I can fit Jantzens. My first choice was MiFlex but they won’t fit without some magic. Same drill with Jupiters. But, Audience Auricap XOs are great caps and they are very likely better than the stock ones.
There are two film caps linked to each of the two massive Nichicons on the power supply. Those are the easiest swap. I’m just not sure how much upgrading these will make. I’ll try these next. I’m very much open to suggestions on make and model for these.
And yes, the V-Cap CuTFs on the preamp gain sockets sound great! I don’t like their price but I do like their sound. :)
