A Care Package arrived this week.  I had ordered two pair of caps two months ago.  I forgot, completely forgot. 

I am now burning in two TFTF V-Caps, they are due off on the 22nd.  Then into the Eros!

You're in the deep water with the big kids now. :)

Rob,

Well, I was making money then and it was a weak moment.


Deb,

0.47uF.  That is the design value for the last stage; same as the Seduction.  The values delivered, there have been two different values I am aware of, are a upgraded film Solen caps.  Upgrade sonically from the brown metalized Polypropylene film caps delivered in the Seduction.

I check the connections to the TFTF caps every day.  The two cats sleep in this room and they are awful about messing things up.  So far, so good.

Sadly... I have not done a comparison yet.  The Caps are burned in and ready.  But I have many other things, house/personal, that have come before my listening. 

Maybe soon.  I'm sick as a dog and not ready to do anything physical.

I put the 0.47uF TFTF in my Eros (tape) and am very happy with the results.

I move the V Cap Teflon's from my Eros tape to the Tube Phono replacing a pair of Auricaps. The difference was immediate and I'm kicking myself for not doing it earlier. The Auricaps are great but I'm a detail guy and the Teflon's seem to get  a little more out of what's already there.

I'm starting a new Eros build (stock first, of course), but have a pair of .47uf audio grade film capacitors that I want to try as well. To clarify, it looks like the design value for the output stage caps is .47uf as per Grainger's post, the parts checklist & schematic show 1.0uf and the included kit caps are 1.5uf. Am I correct in assuming the .47uf would work fine, just changing the bass rolloff point somewhat? Thanks in advance.

Oops, Sorry, forgot to add my name to my initial post.
Dale Norris, located in the Kansas City area. Built a Crack + Speedball with some tube rolling last year. Very happy with that indeed, spectacular sound with HD650.

Yes, your statement about the low frequency performance is correct.

At the time that we put out the Eros, we had the 1.0uF Solen capacitor in our inventory for the SEX amp of that era.  When selecting the coupling cap for the Eros, we simply used the 1.0uF Solen because it was already in the inventory and it is a nice sounding cap.

Currently, the SEX parafeed cap is 1.5uF, so that ships with the Eros as well.

To add a bit here - the output stage of Eros is the same as Seduction (now Reduction). The original Seduction had a 0.47uF cap, which could work with load as low as 15Kohms, but with a trace of deep bass loss, -3dB at 22.5Hz. With Eros, we wanted an upgrade in performance and parts, and the 1.0uF Solen seemed appropriate.
