Hi dirkwright,

To be honest I made it difficult for myself. 15 years since any SMD work, no clip/clamp and no magnifying glass (that I really need nowadays).

I had in mind making a diy clamp but did not get so far. Like this: DIY clamp helps with surface mount soldering well, perhaps it should be a little more sophisticated but just to show the idea.

This is where I'm at now. Still waiting on parts for the oscillator.

HAHA, that's a funny looking thing! Thanks.

Yes, I find it funny looking as well. Nice case you have, almost perfect sized for this application. I seems like a unbalanced output at the back panel. Do you plan to place the mixed feedback circuit in a separate box?

Until I can figure are truly low distortion single ended to balanced converter, I'm not using anything. I designed a basic buffer using one LME49710 and one BUF634 and am waiting on the circuit boards. So, that little board will fit in the box and provide a really low and consistent output impedance for the oscillator. When, and if, I figure out a really low distortion converter, then I'll make another box for that. The all solid state one I have in my simulator uses 8 chips! I'm not sure I want to use it though.

The box I'm using is from Par-Metal.
Par-Metal
It is RFI resistant. The small box I got costs about $100. I'm impressed. It is very well made.

I think Glen found that he could not measure any distortion at all, but that he needed better equipment. So, it should be pretty good at least.

update on the progress on my version of Glen's SVO. I added the buffer board and I have a LM317 regulator board on order for the 6VDC relay supply. Progress is slow unfortunately, since I have so many other things that need to be done.

I am away on holidays now and I just saw this thread. Any boards left, if so I would like one.

Thanks

They are all gone but Glen has the Gerber files up on his website.
