Eros Alternate Build Thread

[xcortes]

Thanks for clarifying. I had understood it the other way around!

Here's a candidate:

Mike Percy confirmed he has in stock the Standard Black Gates 100 UF 160 V at $13.95. That's what I'll use for the 6922 cathode resistor capacitor.

I think I'm done with capacitors. Now to resistors...

This is the on/off switch:

Since it will be mounted from the inside on the frontpanel I will use a #4-40 threaded hole placed on the reverse side.

I asked IAG audio about the thread size of their board and strips. Answer: "All boards and strips use US 4-40 thread size"

I'm in the process of installing AuriCaps in place of the .01uf and .03uf stock caps.  Can someone confirm I have the lead orientation correct before I finalize? 

.01uf Caps:
AuriCap red lead to T4U and black lead to T5U
AuriCap red lead to T12U and black lead to T11U

.03uf Caps:
AuriCap red lead to T2U and black lead to T1U
AuriCap red lead to T14U and black lead to T15U

Basically, just match black to black?

Thx
Chris

You are correct.

Chris,

Do you have enough room in there to stuff the Auricaps in?  Also, how close did you match them and who may I ask did you get them from?

Regards,

Aaron

Xavier, would you be so kind as to publish your BOM? I'll be building my own Eros, hopefully shortly, and having that info handy in one spot would be a boon to all eros builders. Thanks for listening.

My project has slowed down. I have no more BOM than what is documented in this thread. At this point it looks like I will build it in the stock chassis with a few minor part changes.

 

[pro_crip]

I should've been more accurate, I was hoping for a single list of the caps and resistors you decided to go with. Just laziness on my part. Thanks and sorry for any confusion and to doc if I stepped on any toes.

Hey, no need to be sorry for anything! I wish I could have been of more help.

Xavier,

The AuriCaps fit well enough.  I had to hang them off the back side of the terminal strips, away from the tube sockets.  The cap leads are long, so you can trim them to length.  No noise issues for me at all.  PCX will also match caps to a specified value, not just match pairs (I asked).  Their matching service is reasonably accurate - I was satisfied with the result.  I'd bet they would accomodate if you stressed the importance of a very close match to .01 and .015.  IIRC, the .01uf caps measured around .01035ish and were fairly closely matched.  I was able to pair the .015uf caps to .03074uf and .03084uf.

As for impressions, I'd say there's a slight gain in detail.  I may be more impressed after the caps break in.   Time will tell.
