I wonder if you will show us a schematic...

 :icon_rolleyes:

Why? haven`t you caught it from this so-called gentleman`s site yet ?:

Here's some soundclips featuring my now almost legendary lousy but highly sought after guitar style:

Signal path:

Squier Telecaster Custom (bridge humbucker)   >>>   Superfly   >>>   Shure SM58   >>>   >>>   Event Gina 24 Soundcard   >>>   Wavelab

Volume at 12 o'clock:

http://dl.getdropbox.com/u/967492/Superfly%20half%20volume.mp3

Volume at maximum:

http://dl.getdropbox.com/u/967492/Superfly%20full%20volume.mp3

Volume at maximum, with a Big Muff driving the amp (and some genuine submini low voltage feedback):

Sounds great.

I'll be watching the pictures thread for your enclosure work of art for the Superfly.

i wont lie, but the sound clips quality are awful .
you must find an other way to record yourself, cause it should has a real good sound there.

I think he gets the point across well.  I can still hear the amp's character.  Sounding good, Rick.  Now if I can just clear my current project list...

how much current can you squeeze out of nixie power supply?

I don't know Bane. Certainly enough for this application, but as for numbers I've never measured. I just got a new DMM which I think has a setting to measure it, so I'll look into it. Another SMPS that looks interesting is the one in the Blackstar HT Dual - over at the other forum.

thanks Rick!
Most of them I found are 10-20mA. Typical draw for 6021 triode at 100V is 6.5mA. 6112 draws 2mA per triode IIRC which takes us to 17mA. I hope that model you're using on the other side of the scale :)

That may explain one think that was puzzling me. I can get 300 volts out of that SMPS with no load, but when connected to the amp anything over about 210 volts causes it to motorboat. So I'm guessing that as the voltage increases the tubes are asking for more current than the SMPS can supply. I don't know if a bigger value reservoir cap would help any. I settled on 185 volts as the amp sounds good - and loud enough - without having to use physically larger inductors and caps.

I think your work with the sub-minis is way cool.
I too look forward to this ones enclosure as they all have appealed to me so far.
PS I thought it sounded very good as well,you can tell the general tone to be had, probably sound even better with more power.

Rick, your work is almost disgusting, it's so beautiful.  Meaning: it's so darned pretty that when I look at my own stuff, it makes me want to puke my guts out.  It's a kind of art I guess.

Hey Rick what are you using to make these layouts?
And also your schematics I am tired of drawing mine by hand.
Maybe thats why no-one looks at em.

Hey Thanx Rick,
Using Paint did you just cut symbols from existing schematics or did you find a pack of electronics symbols?
BTW the new pics look sweet.
I was hoping for another light up enclosure this time.

I made some of my own symbols, it's pretty easy, some I stole from data sheets and websites- you can steal mine if you wish!

The light up enclosure were cool but brushed aluminium looks nice - and at ~200 volts those little tubes get hot enough to burn fingers, so I'd be worried about a clear plastic enclosure melting around them. Though that would look good too I guess!
