The input caps (2) are 0.22uf and the output caps are (4) 1.0uf caps. The output caps have two caps per channel in series with a feedback connection between the first and second cap.

Which coupling caps are you talking about? Input or Output? George replaced both on his unit.Quote:

(4) 1uF 400v output caps (Yellow square Carli caps)

Here is a photo of mine and the last pic in this post shows the (2) Auricap input caps and then the (4) Yellow "square" Carli caps for output caps
Hey George or anyone else,
I was thinking of possibly using (4) of these for the output coupling caps replacing the (4) square yellow Carli 1uF 400v caps.
Anyone use these before, thoughts?

George if you still have the old yellow caps out would you mind doing a quick measure of them physically?
Thanks

Both input and output caps. Might as well replace both.Quote:

Dunno,,, mine did not have auricaps,,but I'm pretty happy with it,especially after the cap upgrade.I suspect this thing would respond well to some Jenzen PIO caps,I have 4 Obligatto's that were sent (extra),,so if anyone wants em',, they can have them at cost plus shipping.Quote:

I opened up my Dared SL-2000A and found 3 different uf values : 2.2uf, 1uf and .047uf with 3 different colored caps. Would anyone know what caps are these?
pic's please.

I'm using the Dared SL2000A preamp with a Tri 88SE tube integrated amp. Will the Dared render the preamp section of the Tri integrated amp useless? If so would this mean that the NOS tubes installed in the Tri preamp section will have no effect on the overall sonics anymore?
To what extend does the 5Y3 rectifier influence the overall sonic character of the Dared SL-2000A? Is the rectifier as important as the 12AT7 tubes?
Hi Heiney. If I replace the caps they should be (2) .22uf and (4) 1uf, right, not lower? Did the original Dared SL-2000A come with all (6) Auricaps? Would it be good enough just to replace just the (2) .22uf input caps? Thanks.Quote:

I think I prefer the Brimar over the Bendix.Quote:

Can I use 12AU7s in lieu of the Dared SL-2000A's 12AT7 tubes?

No, but you can use 5965's which are about the same gain wise.Quote:

Hopefully by the end of the day I'll have a new rectifier on the way. Like I said, I just had to bid, win and try these out. I'll post more after the auction ends.
