I'm rebuilding my modded Dynaco ST35 amp into a new box.

Kinda like this...

Thanks! Too bad the system at my workplace won't let me see the picture...  :(

 Good lord, that's a little above my ability. Now will any of the wiring have to be rerouted because of the new box, or is it part for part, piece for piece?  I was sorta thinking along the same lines for the Quickie.

It's pretty much my own layout.  Here's what it used to look like. 

(https://forum.bottlehead.com/proxy.php?request=http%3A%2F%2Fi576.photobucket.com%2Falbums%2Fss207%2Fcorndog642%2FDynaco%2520ST35%2FIMG_7465_zps4e68055d.jpg&hash=ca74d714c5255cc8dadc9e26af94c02c90b15c08)

Which was also my own layout.  I wanted to do something different.  I succeeded but over time I realized that I actually made it harder to deal with troubleshooting and/or making changes. 

The new layout will be much easier to troubleshoot and tweak.  There really isn't a lot of parts to these amps.  It seems like there is but they're  deceptively simple.  I should be done building it hopefully later this week.

adamct - Sorry you can't see my pics.  Maybe you can see this one.  This is similar to my idea but a little different.

Thanks, Rob! That one worked.

I've got to try my hand at breadboards. They are more logical to me and keep things neat.

Can someone post a pic of the non-component side of a breadboard? I'm not clear on the proper way to wire up components. And my few attempts have ranged from ugly to disastrous.

Thanks

It's pretty much all point to point with some wires used for longer stretches.

(https://forum.bottlehead.com/proxy.php?request=http%3A%2F%2Fi576.photobucket.com%2Falbums%2Fss207%2Fcorndog642%2FDynaco%2520ST35%2F0db3f02d.jpg&hash=e1d0728db753be4945865d8ab7902cc0eb31ad7b)

In the next version I'm only using a pair of small bread boards for the negative feedback circuits.  The rest will be mostly point to point.

I am also planning on a rebuild of the ST. 35. However, I will do something a little extreme, by using different tubes, and building mono blocks. I will be using 6SL7 & 6SN7 tubes in the front end, and 6V6 tubes in the output, and installing the new PCB's.

Funny, I always hear all these great things about the el84 tube. I was also thinking that maybe the bottlehead crew can design a simple but quality el84 amp to go with the quickie or something like that that can rival the st35.....just a thought...

Am I on the same wavelength here or what?...  Before, I posted, "what would be really cool to see is a DHT OTL reference pre amp". and Doc came back with , "we are already working on one"... and now, I ask about an el 84 amp, and Doc is "already discussing it"...   I promise, I am not remote viewing or spying Doc... :)
