Finally after 1 year of making, testing, playing and design, I finish my tube preamp Di box.

I know the amount of work I put into squeezing a Superfly into a 1590A, so I can easily see how this project would take a year to finish, and mine didn't look half as organized as yours.

Thanks guys. Yes, Ben N. I use grommets to reduce the risk of breaking the tubes and the shock of the tubes. I think that this is typical for device like this where small tubes are used.

EDIT: Also I make a lot of tests with different tubes and my choice was JJ premium gold tubes with long plates. These tubes gives the best sound. The only one disadvantage is the price - 20 euro per tube or 40 euro for tubes inside one unit. The sound is really great. I test this preamp with more than 10 basses - Fender precision, jazzbass, another marcus miller active jazzbass, musicman stingray, 2 warwick basses and a few boutique basses. The sound in all cases was great, but the best what I hear when play was from classic fender precision and jazzbass. Soon I will make some video presentations.

Here's 3 decalled enclosures awaiting drilling and, of course, their circuits.
They're a Shoegazer (should have gone for white paper, the magenta/red loveless combination didn't turn out as good as I hoped), a SHO and a BM treble booster.
First go at waterslide decals, very pleased with the results. Will lacquer tomorrow and let cure as I solder the boards together in the next few days.
Will post photos of the finished article next week, hopefully taken during daytime, the flash doesn't do them justice.

Pedal made from a circuit bent hanna montanta toy guitar board. Sprayed a vintage metal box for the enclosure. Not the best, but I'm still newer to this stuff and learning alot from this forum.

It works!

It's R.G.'s Phase 90 Plus, using my own layout. Fets are 2N5952. LED flashes green in time with the LFO when bypassed, and flashes red to yellow in time with the LFO when in use. I plan on some minor modifications in the way some of the controls work to better define their ranges, so I haven't stuck the standoffs yet.

It sounds really good.

Brilliant work.

Swirl's not usually my thing, but that looks great! Where's the box from?

@alex spaceman: You should have drilled the holes before you applied the decals! If borings (correct word? "Bohrspäne" in german) get between the enclosure and the decal, it could be destroyed...

Terrific looking build Niki, as good as it gets, and brilliant idea for the tube retainers!

Maybe shavings?  Your English is far better than my German!

^^ Thanks, Dave!

This is one of my project which I start doing first for me. I'm bass player and I spend really a lot of time of thining, tessting playing etc. Yes, It becomes great unit, but typical for a first PCB desing there are some small thinks to fix next time to become perfect PCB design. Making PCB for tube unit with a low noise for studio is not a easy job too.

@Nikolay

Do you work in a PCB fab house? It seems that every post of your builds contain a fabbed and screened PCB 

Do you do this yourself or do you have them done in a fab house?

^ cool echo base ca cat.....and a metal washer .nice!...



@mike: came out nice !!!!..

Govmnt, I work at home. Some of my stompboxes are with doublesided pcb when they are more than 4-5. Of course I order these PCB's. If I need to make just single stompbox, I make it myself using laser printer technology.

And where do you get those enclousures? And graphics on pedals? On some previous pedals/units I have noticed faceplates. How do you make theese? Etch or laser engraving?

[Nikolay]

When I need coustom enclosure, I make it on 3d. Then from 3d I get the sketch for laser cut. Then bending.
Some frontpannels are from black anofized aluminum sheet or from steinless steel. Both of them are laser engraved. All other labels are with silk screen.

I got the enclosure for a forum member here. It was a b*tch to drill. I had to grind afterwards to get all the burrs off.

Thanks. What a fun effect!

I realized that I never posted pictures of my multi-booster after I got it all put together and (mostly) tamed. I learned a lot on this one.

PNP Rangemaster -> Crackle Not Okay -> Minibooster -> Tone control (based on Colorsound Overdriver) -> Volume control.

Each boost is switchable, and when they're all off, it's a buffered tone/volume control. Really it's a utility box.
