ValveLiTzer Tube Booster

[thecactustube]

Sounds great!

[userboy6]

OMG i love that thick sound!

[daxweb]

can a booster to wide the stereo front? strange...or maybe post processing...

[TheWarped45]

wow sounds fuzzy with some crunch.

[wizdum25]

Was the Kay 503 modded?

I am really looking for this sound.

Anyone recomend a DIY pedal that has this "vintage early breakup" sound? What makes it hard to find this sound is not knowing how people describe it.

[Lovebug1327]

Can I order one from you? In a smaller footprint ..?

Thanks

Nick

could you make this with a compactron tube wich is a triple triode ? so it'll have 3 gain stages instead iof two ? I don't have the skill to do it, maybe you do. Cool stuf

[gggmoon]

I dunno--several low-voltage tube overdrives have surfaced recently. I didn't know if this tube would work until I tried it.

Low voltage (starved cathode) operation is outside of the original specs, and the only way to know for sure is to try to build one. I don't have the tube, so it's up to you...

Good luck.

[bob505470]

its posible, i dont know of any compactrons that run low voltage though. shouldent be two hard to make though

[LyricalPoet777]

what is that amp? sound perdy good without pedal to begin with.

[gggmoon]

A little Kay 503, miked.

[clayton5150]

so is it starved plate? cuz it sounds better than starved plate design.

[gggmoon]

Yep, it's gotta be starved plate at these voltages...

[clayton5150]

wow it sounds realy good for starved plate! people bitch and complain about that setup but its much better than silicon!

[Joni0001984]

Tell me about your amp. It almost sounds better on bypass. =)

[gggmoon]

Sigh. I tried once to answer this (utube hates firefox.)

This is my little Kay amp. I sounds good 'cause it was miced, not just recorded with the on-camera mic.

[stupidplants]

is there a way to make this a little dirtier? (well more like alot... but i could put a DS-1 in front if i had to)

[gggmoon]

The gain is limited in this device, because it's running off such low voltage. So there's probably no way without redesigning it for higher voltage, and that would require a separate power source for the filament.

You could push the front end with an FET booster, but then you might as well go all silicon...

As it shouldn't work at all with a voltage 1/15 or less what's normal--just consider it a low-voltage curiosity.

[stupidplants]

what if i were to put 15 to 18 volts DC to it?

[gggmoon]

That's OK--IF you use separate voltages for the plates and the filament (it's essentially a lightbulb and will burn out above 13V.)

I've added some changes since, and it's got a bit more gain and dirt...

[stupidplants]

one last question... this into a solid state amp... tube/hybrid amp tone? a nicer solid state tho. fender frontman 15R (with built in spring reverb) to be exact .

[gggmoon]

It works nice with a small "Decca" SS practice amp I've got... Don't see why not. (just got back from vacation, or I'd have seen this earlier...)

[NARCOPOLO76]

when you mic your tube amp and send it thru the the sound system you are doing the exact same thing.

[Renegadrian]

Nice project...THX for sharing it - I have to get one of those tubes...

[OpteronMan]

Nice job!
