[sdiy] Formant and ASM-1

[Gene Stopp]

OK I must admit the tube ladder VCF has caught my attention. If we can put
together a cascaded transconductance lowpass out of vacuum tubes (with
resonance of course) I'd be all over that. Are you listening Eric? :) Is
this possible, or have you baited us in the hopes that we will get off our
duffs and own up to some thermionic experiments of our own? Now I must admit
that when I woke up this morning I had no idea that by the end of the day I
would be quietly distracted, tallying in my head just how many tube sockets
I'd need to find, and whether or not that un-used NOS 375-0-375 VAC
transformer on the garage shelf would be a good starting point? Oh yeah then
there's those nice coke-bottle 5U4's in the drawer... and I do have an old
Wurlitzer chord organ somebody gave me that's not working... it's got a few
dozen 12a-something-seven's in it... hey! Lookit all them sockets! Better
schedule a trip to All or Apex to get some 1/2 watt resistors...

My wife will soon figure out that something's up... I'd better be careful.

Is there a schematic for what's been tried so far? Did one already fly by
today?

Best Regards,

- Gene

Ah, lovely, some self-criticism at least.

Haven't you read Synth-DIY lately? Tube-ladder? Hallo??? Here we are
running around in wierd circles and mess with fundamentals... if that
doesn't count as hardcore and Mad Scientist then you've been on
Synth-DIY for too long! >;O)

Oh... ahh.... I recall when I had Byte and read Circuit Cellar. I
dropped out on my Byte habbit when they lost character and dropped
Circuit Cellar among other things. I liked when they where digging
into hardware and stuff. You learnt the machine by that.

I also had the Swedish variant of Elektro, Allt om Elektronik ("All
about elektronics") which I grew up with. They had their store (and
only store) just 500 meters of my school. Guess where I hang around?
They too somewhat dropped out of interest. Still some semi-interesting
projects around, but they doesn't give me as much. I guess my level of
advancement prohibits me from getting the same kicks from that journal
as it used to. Now days I have to get my kicks elsewhere... (no,
Champain doesn't do it!)

Cheers,
