Just received some "Mundorf" capacitors. They are well-known for their standard lines of capacitors, M-Cap (MKP), Tin-foil, and unique-made "Supreme" serie, now expanded with "Supreme Silver/Oil", and for the most demanded, "Supreme Silver/Gold/Oil".
They have brand new capacitors for tube amps power supplies, "TubeCap" serie (polypropilene), and "M-Lytic HV" electrolytic caps.
There are not too many distributors, especially for the whole program, but I have luck with their local distributors "Hornet Audio" (http://www.hornet.hr/), good service - reccomendable.
The price for those 9 capacitors is about $250 with tax.
From L to R:
-pair of 0,22µF/1200V "Supreme Silver/Oil" coupling caps
-four 47µF/600V "TubeCaps"
-pair of 47µF/400V "M-Caps"
-one 200+200 µF / 500 V "M-Lytic HV" capacitor

P.S. Of course, I have no affiliation with "Mundorf" and "Hornet" companies other then being the customer. I posted this just for information to other Tube DIY-ers.
