Eros build progress pics

[JamieMcC]

Hey guys I’m really enjoying the Eros build so far and as soon as my little ones are safely out of the way upstairs enjoying their bed time story with mum I get the chance to reclaim our dining room table get the soldering iron out and make a little bit more progress.

All has gone reasonably well so far and tonight fingers crossed the goal is to successfully completed the transformer tests and check it off the list.

Here are a few progress pics of how its coming together for you

You might notice the 5W 270 Ohm cement resistor which is sitting close to the pcb board the one from the kit was missing and I had one which I had pulled from a Crack when changing it for a choke there wasn’t much left of the leads so it went in but I ended up swapping out for a metal shielded one I had a couple of in the parts box so its stands off of the pcb a bit more. As I have a couple of chokes as well I suspect I will try one of those out at some point in the future.

Looking good so far! Have fun and take your time. I just finished mine and will be posting on it soon.

LOL Doh where is the face palm icon no wonder I couldn't see a big white cement resistor I should have been looking for a big green one instead  :-[

Edit At least that was a easy fix

I envy the carbon!!!

Nice...very nice...  8)

It is looking good. I like what you have done with the carbon wrap.

I have the power supply installed on mine and moving onto the shunt reg. Can't wait hear how it sounds.

+1 re: the Carbon Wrap. How do you do that?

 

[JamieMcC]

I glue a thin real carbon fibre veneer to the Eros top plate (gorilla glue) then use a dremel with a drill bit fitted to cut out the holes by following the edges of the cut outs and using the spiral part of the drill bit to do the cutting from the non carbon side.

Very cool. Sort of committed to the red spray job, but would love to try that on the next project.

Snap thats just about where I am up to now

I still need to wire the heater, so you are ahead.

I did not work on the circuit last night, but plan to get a lot done this weekend if I can find the time.

I built the CCS boards with the servo, but I'm thinking of removing it. As I get closer to installing them I will decide.

I also, ordered more 6BR7s, so that I have a good stash of them.

 

[JamieMcC]

I've been up and running for a few hours now and the Eros is sounding very nice

The end was nearer than I had thought, after spending about ten minutes chasing down a couple of odd readings on the resistance checks I moved on to the voltage checks and all passed with flying colours.

I still have a few more mods in mind but going to enjoy the fruits of my labour for a while and celebrate with a wee dram.

Cheers Bottleheads

Congrats on finishing the build!

Looks great!  The Eros is a great preamp.  Since I built mine, I've found myself listening to vinyl much more than any other source.

 

[ALL212]

COOL!!!  8) 

I'm with Rocketman248.  I've not pulled so much vinyl as I have in the last week as I have over the last year.  And now shopping for more...

I also finished my amp today.

Had some resistance readings that were a little higher than the manual, but they were consistent between channels so I moved forward with the checks. I powered it up and all the LEDs lit up and the readings were good. I was concerned because I could not see the heaters in the 6BR7s and was not sure they were getting power. I figured I would put it in the system and see what happened.

I connected everything and threw the power switch, nothing. No sound, no pops, nothing heard through the speakers. No tube hum coming from the speakers. I continued with testing the Eros, but was thinking there was a problem. I put Led Zeppelin's The Song Remains the Same on the turntable cleaned the stylus, and there it was, sound coming from the speakers. That was a very positive sign. I dropped the needle and music came forth and filled the room. My fears of a problem washed away.

I only listened for about an hour and a half. It sounds good so far and wish I had more time to listen. I'm going to enjoy breaking it in.

Congrats Brad!

When I first tested mine I used the tubes that came in the kit.  It worked.  Turned it off and put in "my" tubes.  Turned it on...no sound.  Now I was pretty worried at that point until...

I realized I hadn't put the needle down...

Congratulations I was up late last night enjoying a few LP's and you know how it is once you start its hard to stop!

Devialtions from stock are Cardas ground lug, Kiwame 75K 1/2W & 47K 2W resistors. The Ampohm paper in wax tin foil capacitors I have had for a while after using them in my Sex so it would have been rude not to try them as they are very nice sounding caps.

The plan was alway to go with the Teflon ouputs caps and I replaced the Ampohms with the Russian Teflons today (0.22uF 600V FT-3) you really got to love those Ruskies  ;D  the Teflons sounded superb from the get go and will only improve once they have a good burn in.

Russian candy yum yum  ;D
