[Heath] SB-610 Monitor Scope

[Robert Groh]

Nope. 


One of the joy's of good ol' point-to-point is it's simplicity.  If I was going 
to update a unit, why wouldn't I just want to make a big jump instead of a 
little jump?  I usually don't make the big jump but that is not necessarily a 
good thing.  So just a little thinking outside the box.

You’re joking, right?

Missed the beginning of this thread but the thought certainly occurs to me that 
one might be a lot better off just skipping the idea of keeping the CRT et al.  
If you want to keep the looks of the SB-610, just gut the SB-610 and then put 
one of the new small little notebook computers or eReader or what have you 
inside it for a display.  Hook up some analog to digital converter blocks and 
write a little (?) bit of code and away you go. In fact, go color if you can and 
you can really get fancy.

Bob,
 
There is an effort by Dave Cook, WA0TTN, to covert the SB-610 to solid state. 
That may or may not be what you’re looking for but here is some info for your 
review.
 
He sent an update on his efforts to me in July but I haven’t seen any posts from 
him since.  Since I am directly copying him in on this message, maybe he will 
let us know how things are going. 

 
Here is what Dave said in April in his first summary to this list:

Well first of all, I thank you all for the overwhelming response to my query. 
What a great group! I think I got the answers I was looking for, and then some. 
Here's a summary of the responses, both on the reflector and directly to me:
 
1. The general consensus is that converting my SB-610 to solid state is a 
reasonable idea.
2. I took a look at the SB-614 and HO-5404 schematics. I didn't know these were 
solid state scopes. But I found they're both using all discrete transistors, 
c.a. mid-1980's and the circuits seem a bit elaborate when compared with the 
simplicity of op-amps circuits. Still, I got some good general ideas of how the 
early inexpensive transistorized scopes were designed.
3. I got my parts order for this project from Mouser today. The HV transistors 
I'm using for this project are only $0.20 apiece and the wideband low-noise dual 
op-amps are $0.60 apiece. Kind of difficult to justify buying a junked SB-614 to 
salvage the circuit board when these parts are so cheap.
4. Several of you expressed interest in collaborating on this. I'll contact you 
directly, offline.
5. I'll most definitely post my results to the group after my first prototype is 
completed. It might even be worth a QST article.
 
Thanks again for all of your opinions and suggestions.
 
73, Dave WA0TTN

Has anyone re-built a Heathkit SB-610 Monitor Scope and used a PC Board rather 
than point to point wiring.
I also have an HO-10 that needs to be re-built and would prefer to use a PC 
Board rather than point to point wiring.
