If it was me, I would look to Mundorfs or if you can afford it, the V-Cap Teflons. I have swopped al of my AN caps out for V-Caps, and the sound is more transparent with stronger dynamics and bass.
I do think Peter sorted the issues with the newer Mylar caps though, but by then I was fed up with 3 x failure situations. In my case it led to DC leaking through to the volume pot (static noise). Thankfully didn't blow any tubes!
BTW the Mundorfs and the V-Caps are VERY load and heat tolerant, important in a Valve amp IMHO. Go Mundorfs if you are tight on money. The V-Caps are REAL nice though, and remember, the cap change will alter the sound more than tubes or interconnects or resistors. For me it was the better.

Yes! I already changed out my signal coupling caps (C7-C10) with Mundorf Silver/Oils last week... I liked the sound initially, but now I am in that 300-hour burn-in and they are pretty bright. I think I will like the sound (and reliability) once they are burned-in.
However, my question is about the DC/ high frequency filtering caps (C1-C4)... do they affect the sound?

those caps are used to filter out high frequencies outside the audible range - they are located between high voltage HT and ground - do they make a difference to sound? The amp will work fine without them - possibly you might be able to tell the sonic difference without them vs with them but the type of capacitor will not make a big difference - you basically dont want to put in expensive caps in these positions - you want caps that are very robust and can handle a constant 450v DC- Brian Smith

Thanks Brian! I'll solder in those 1000v Solen metalized polyprop. I think they will probably be more robust than PIO caps!
