“Vintage Vibe” Low Voltage 6111 Submini Tube Vibrato

[kurtlives]

Could two 12AU7s be subbed for the 6111? EDIT: Read the opening post, so I guess so.

With two 12AU7s with 12V DC this thing would draw just over 600mA wouldn't it?

Again, beautiful work Rick.  That rainbow ribbon wire makes me so jealous, but glad the 7327's are working out!

Thanks Willy, though I've got to stop work on it for a few days to build a 'Murder One' for some dodgy geezer.

Your idea of writing the component values on bits of tape like that is sheer genius.

Thats because I can't read resistor colour codes - I use a multimeter to check them.

Love all these tube circuits you've come up with, I must source some tubes and start playing.

Thanks! And yes you must!

Hi Chris,

A 12AU7 will draw 150ma @ 12.6 volts. Or 300ma @ 6.3 volts using the centre tap. So two 12AU7 @ 12volts will draw 300ma. Or you can use the centre taps and run the two tube's 'half filaments' in series - that would still draw 300ma.

So the answer is that yes you should be able to sub 12AU7 for the 6111. And whether you use 12AU7 or 6111 the current draw will be the same. If I were using two 12AU7 I would run both the tube's heaters at 12 volts and leave the centre taps unused.

I have just finished my build. I built directly from the layout that I posted above, so I can verify that the layout is 100% correct! 

Photos to follow......................

Hmmm...  I resemble that remark!

Here's my completed pedal, works a treat and identically to the version still on my breadboard.

Excellent work!  That's a beautiful build!

Looks great Rick!

I am contemplating putting a similar circuit in a pre-amp I am working on. So does it use two LDRs that are joined with one LED?

Thanks Chris. Yes, two LDR's and one 3mm red LED is what I used, you can see them mounted together on the oscillator board here, bottom left:



I didn't have to encapsulate them, as I thought I would, though my enclosure has vents in and a status LED. I just put a piece of card (a cut up submini tube box - what else!) to isolate the LDRs from the vents and the status LED. You can see that clearly in one of the gutshots. You may have to consider sealing the LDR's/LED against external light sources depending on the nature of your build. Having said that, even with the back off the enclosure the effect still works, it just isn't very deep.


EDIT: I can't vouch for how the LDR's/LED will wok with different size or different colour LED's to the one I used. I guess you would have to tweak the resistor value that is in series with the LED and Depth pot.

hot damn!

sounds so sweet i melted .... seems like the vibrato i'd definitely use on vibraphone or piano for some tiki-lounge vibe (no pun intended)

great!

Hey Rick

Which effect would you recommend to use for a surf sound? the vintage vibe or the vibecaster?

If I go with the vibecaster, I could just add it to my existing valvecaster. The valvecaster is running at 157 volts DC two transformers back to back 120/12-12/120 I'd run the transistor portion at 12 volts of course :-)

Being a British rock type, I only have a vague idea what surf sound actually is...........in my book there are only two types of music: Rock 'n Roll.

Have a listen to both soundclips and judge for yourself.

The Vibracaster mod is so easy to add to an existing Valvecaster, you should do it anyway.

The Vintage Vibe is different again, getting almost into chorus territory.

Do both!

So you don't know bands like The Shadows?!
They are British!!!

Yeah I know The Shadows - I used to be in a band many years ago with the daughter of Tony Meehan. The Shadows were surf sound? OK!

[Renegadrian]

A lot of their songs are said to be surf, a little different from the Beach Boys stuff, my sicilian friends from Adels are also Surf sometimes, check'em out on --> myspace

I love the track called El Siciliano, tipically Shadows...

Love it - very Quentin Tarantino. As a kid I was obsessed with 'Apache'.

Yeah, we're relaxing and going a bit OT...Back to my breadboard, there's a 12BL6 waiting for me...

Adriano!
Your right that song is great!!!
Now thats surf!
And the song called Don't call me daddy. It's surf meets rock-a-billy

I was at your site and listened to your stuff using the vibracaster Surf Rider nice!

Hey, frequencycentral, did you alredy made a phaser?
Have you seen this one - http://www.solorb.com/elect/musiccirc/liquidator1/index.html

If I had already made a phaser you would already know about it! It's next on my to-do-list, at the moment I'm busy building a few Murder One amps for people and finishing my Sub Zero design.

Yeah, I saw that phaser you linked to, Mark Hammer posted a thread about it a while back. It's a big piece of kit! And full of transformers. Mine will be submini............
