Oh, by the way, the board looks great!
Looks like good registering between the top and bottom.

Any new pics of the build?

Not yet, I am still waiting on my remaining parts to come in. I couldn't get a hold of some caps on the BOM so I wanted to wait till I got the alternate caps and make sure they fit the spacing before I start soldering anything.
 
Have you ordered your parts yet?
 

 

[Pingupenguins]

No not yet. I'm still working on the board. Where'd you get your tubes and sockets?

Thats what I was looking at.

 

[zammykoo]

I got them on ebay, I think anywhere else would be too expensive

 

[Pingupenguins]

Can I clarify that the tubes are 12au7 and the sockets are pcb mount 9 pin?

 

[zammykoo]

Yes, and for the sockets make sure you get the through hole sockets for the pcb, not the screw on kind.

Some of the alternatives, like the 5814 etc. are the same tube, but just relabeled, and generally a lot cheaper.

 

 

[Pingupenguins]

Anything to be updated? All your parts come in yet?

 

[the_equalizer]

Ah! This is looking really neat so far! It's really nice seeing more specimens of the SSMH coming to life. Good work !
 

 

[zammykoo]

Thank you, thank you.
 
Sorry fellas, I have been super busy. Been preparing for an upcoming job interview so I had to put this on hold for a little while. Hopefully I'll be able to revisit this project toward the end of the month. *crosses fingers*
 
I have also ordered parts for the O2 amp so I will be building that as well

 

[zammykoo]

Had some free time today to start putting the components together finally! The solder job is less than pretty because I had a shotty iron, didn't have my good one on hand.
 
I am still missing one key component... the bergquist pads. Can I just use some of that thermal grease used on cpu heatsinks?
 

 

[jamesbobo007]

Looking good !!
your using 2 heatsinks right? For testing, as long as the heatsinks arent grounded you can just use thermal paste.

Oh cool, that's perfect because I am using the vertical heat sinks. I'll give that a try.

Nice Tam. what tubes are you putting in? Also the I just checked on the guy who is making the planks of wood for me and it's looking good. Im doing test cuts tomorrow and ill then put the planks in CnC soon. Still trying to get copperclad board.

hi guys,
do you have the schematic for this tubes headphones amp? n also the pcb layouts? please
