CRAZY HUGE VERO!

[johnk]

I just finished drawing up a vero for the Musitronics Phasor II. It has 7 chips (counting the voltage inverter for the dual supply), one transistor and THREE dual vactrols! that's SIX optos!  I still have a vintage original one and i love it, but I wanted to build my own slightly smaller version that runs on a standard center negative 9V supply. the vero is so big that it won't even fit in a 1590BB. it's going to have to go into a 1790NS (same size as a Hammond 1590XX) but that's still smaller than the original that runs on 120VAC.
i'm almost embarrassed to post it since it has so many cuts and links (and even some stand up resistors) but I just couldn't get it any smaller (for now). i''m sure that IvIark could since he's great at drawing them, but I doubt that he'd even want to bother drawing this one up.

looking at the schematic, it actually appeared somewhat simple (until i started drawing it up!), so here's the schematic for it.

There's no way it's any bigger or crazier than Dino's infinitphase vero, post it up!

[johnk]

well, it's pretty close to that size.

it's not verified yet but I've been over it a zillion times so i'm pretty confident that it'll work properly.
I plan on building it in the next few days.

Awesome, nice one John

That's Tayda's profits gone through the roof

Some serious work there John - mmmm looks like a challenge  
no .. no .. no .. must be good - have some other to do ... must do first

[rocket88]

man, if john says the original is good and he still has it, then it must be worth a build. can't wait till its verified.

[johnk]

just an FYI. be sure that you always refresh the page to get the latest vero since I've updated it a few times now.

i'm just waiting to for my three VTL5C3/2 vactrols to get here and then i'll start the build, and (hopefully)can verify it.

Haha

[johnk]

youse guys is funny!

[johnk]

well the VTL5C3/2's came today so I got started on the board. it took me just over an hour just to get it this far! (91 cuts with 56 links is a bitch)




tomorrow, all of the components are going to be added, then i'll test the layout.

Massive! Just about as bad as tackling an AD/A flanger on vero

Where do you get that Green stripboard from? Never seen that kind...

[johnk]

I get the green vero locally.

........and it's VERIFIED!!!!!! YAY!!!!!!!!!!!!!!!
I can't believe that it worked perfect the first time with NO troubleshooting.
and it sounds AWESOME!

[IvIark]

Awesome job John, looks fantastic

[jalmonsalmon]

 WOW...
GOOD JOB!  I may have to try this one out if I get brave LOL
Demos of this phaser  sounds too good...
