SissySIT P ..... or how I proved fact of making more Hats than Pa did

[flocchini]

nope

La Zucca imagined with resistor (relays) binary matrix attenuator

2^6, 64 steps of ~1db

Iron Pumpkin is one and only; if someone needs both exquisite attenuator and different gain stage than it's already given with autoformer, then just use Iron Pumpkin as exquisite attenuator and whatever outbox gain stage is adequate

there is no easy way to physically combine Iron Turtle, necessary buffers , regs for them ( all that being Iron Pumpkin already) and additional gain stage ...... all of that in one box

understood

gone today to visit my Official Second Set of Ears

You sold me a long time ago.
The issue is always the time and resources to make one worthy of the design.

I am still waiting for IP to become available on this years Black Friday

Yet another to add on to my already long list of things to analyze, attempt to learn, and maybe even build. I'm trying to reverse the order now. I used to just build everything before even trying to understand. My reward for learning is the assembly ... and solder fumes.

Still, too many ZM projects to come before. Have to get Singing Bush in the chassis, then the LuDEF is next ... and of course ... the Pumpkin. One reward for me being later with this project is by the time I am ready to build it, you'll have R.3 boards ready.

I realized it's exact recipe for disaster ...... no, make it - DISASTER!

just imagine scenario of regular Greedy Boy being utterly confused with number of jumpers, parts not needing population for actual iteration of amp etc. ....... and each one pulling me to help with dilemma ( in best case) or help to put gray smoke back (much realistic scenario)

The Piñatas don't release candy when exploded!?

..... by the time I am ready to build it, you'll have R.3 boards ready.

.....

luckily, did learn thing or two with SissySIT revisions, so now there is no need for revisions of succeeding ones



now, just wishful thinking - why I didn't stumble on on SissySIT R.3 principle, from the start?

heck, even Pa did revisions of his products ..... can I hope to be smarter ?

La Zucca...

You're a volcano of ideas, MightyToi!

while in Office, some new drawings, just to incorporate last Unobtanium

 

[Robin De Wolf]

Hi ZM, will the P iteration be available as package anytime soon? I have one more set of thf's that I'd be happy to give a proper home

 

[Zen Mod]

ha

that means ZM forgot to post Trade Thread ....... not one, not two ........ more of them



send me an e-mail

Hi ZM,

I would like to try something with my current DAC. It has balanced output floating 2.7vdc above gnd. Say I want to feed it directly into the Sissysit (or XA252), balanced. Could I then jumper C103 so that both positive and negative signals DC are offset leaving no or very little DC offset at OS?

 

[Zen Mod]

I wouldn't do that

install decent caps or xformer at output of DAC; they're much lesser evil than taking any circuit out of optimal range of operation

I tested everything possible with any of my amps, but I never tested their power On/Off behavior with inputs moved to different voltage level

I mean, you can do/try that, but I can't promise anything

 

[Robin De Wolf]

Thanks! I will follow your advice, this does not sound like a decent approach to pursue, got it
