Looking for advice on the coupling cap in the SV811-10 I'm building (see link for schematic.) Looking for 2uF @ 400VDC. Anyone got a favorite flavour?......Colin

I'm running Kimber Kaps in the Stoetkit, and I like them very well. Other high end choices include Auricaps, Musicaps and Audio Note.

On the subject of coupling caps, a note on Audio Note (no pun intended). Audio Note paper in oils are made by Jensen Capacitor in Denmark, and are identical to the caps sold under the Jensen name or the paper in oils sold by Angela Instruments under their own name.

I've bought these PIO caps from Angela Instruments many times, and sometimes they'd say Angela, sometimes Audio Note, and sometimes Jensen. Angela's owner, Steve Melkesethian, verified that they are all identical save for the superficial exterior markings. What they sold was whatever stock Jensen had on hand and sent them at the time they ordered them.

So why did I mention this? In the hope that one it'll keep one of my fellow DIY tube nuts from getting burned! Audio Note branded caps sell for about twice the price of Jensen branded caps from most Internet dealers. You pay twice as much for .001 cent of lettering ink!

Yeah, but do the AN caps SOUND better? IF so, they may be worht paying for?

Certainly! Unbiased listening tests among a random sampling of conceited, golden-eared audio snobs confirmed that the Audio Note caps beat the Jensens hands down. Independent laboratory testing has also proven that the shape and form of the Audio Note logo printed on the cap is 233% more effective at focusing supernatural interstellar cosmic audio karma into the cap than the Jensen logo.

Pweeew! And I thought I might have wasted all that money. I feel much better now.

Audio Note capacitors have NOT been made by Jensen for a number of years now. Angela instruments may have some old AN caps from the time when Jensen did make the AN caps, but that has not been the case for at least several years now.

Skepticism is healthy; cynicism is not. Fact checking is always good.

To put a time reference to this, here's a response from Peter Q. back in Jan 2001:

Also, FYI - Steve at Angela Instruments last purchased PIO caps from Audio Note in 1996, so this is really a very out-of-date observation, unless he still has some 9+ year old caps to sell, in which case, the comments would apply to those caps only, not any of the Audio Note caps being sold anywhere else here in the 21st century.

After switching to DC heaters in my 300B SET I preferred the Jensen/Audio Note/Angela (?) paper-in-oil caps. I found AuriCap and Multicap RTX too dry and Vitamin-Q and Russian oilers too slow and muddy (but with killer mids). The AN's just seemed to be the best compromise in that circuit.

In my AC heater 45 SET I love the Jupiter caps, might be the best of the bunch but I never bothered to swap them out to compare, I just like it the way it is.

Hovland caps? [message #11151 is a reply to message #11150 ] Tue, 05 July 2005 18:55 Go to previous messageGo to previous message

Any experience with Hovland? I've heard good things about the Jupiter caps, but they do not come in 2.0uF 400VDC, which is what I need.
