Very nice!

Have you got any close up shots so we can see what the modules are?

formant rebuild

2003-05-09 by the19thbear

it IS possible to do a replacement of the ua726... i just did it, and 
its not that hard.. i cant tell any "sound quality" difference here..
right now im just using two transistors instead of the ua726, but one 
could use the lm3046 and then have a resistor to warm the thing up 
above room temperature..to archieve better tuning stability..
i have one working vco, but another thats not working.. one of the 
ic´s get very hot when i turn the thing on.. i have tried to replace 
it but nothing happens... i suspect one of the transistors are toast..
too bad, 
and by the way.. 
anybody got the 12db filter? does your res/octave pot worke reversed 
when you put it in HP mode`?? mine does, and its not fully working.., 
it has this weird noise..

If anybody needs some ua726's I have a secret stash that I've been saving.
I don't mind selling a few off for those in need.

HOW exactly do you do that? i'm thinking of building a stripped 
down formant into a gutted poly-61 body, think it's possible but 
still thinking instead of doing it. (tests and papers deadlines on 
the horizon... not that much free time on my hands right now...)

well... you find the specs papers for the ua726,and the spec papers for the 
ca3046 and find out what pin is e,b,c and then you take a little perfbord or 
something and solder an empty housing for a 16pin ic on, then you connect 
the correct wires from your formant vco to your empty house, and then you 
put an ca3046 in the house, and then...voila,  it works perfectly, i didnt 
even need any temp. control, the vco is stable!!

ill draw a precise schematic for you within two days or so, if you need it

Boy, i can't believe i was that lazy, to ask a question like that, 
guess your expanation sounded too complex for me, haven't had 
much sleep lately... Anyway thanks for the advice and the 
patience
