Zonk machine!

[Johnnyorange500]

On my way to finishing my zonk machine first edition all germanium transistor set-up soon! Will post more on completion! Painted the enclosure quite happy with the colour and finish on this one!
Cheers

Hey man! Nice to see you got the enclosure painted! It’s looking really good

Cheers, much appreciated. Yeah, couldn’t be happier how it turned out.

Got the decals on the zonk. On to the next stage!! Ignore the knobs, I’m not using those on the Final build.

That's a great idea to mark the off position for the knob indicator. Does the circuit have a minimum pull down resistor? I'd be tempted to build a fuzz that didn't and mark both the volume and gain knob that way. This looks really cool leaning into that retro vibe.

Hi buddy.

This build features the original on/off power switch integrated in to the "swell" control, so you can leave it plugged in without draining the battery, as long as you remember to switch it off. It’s just a replica build of the old original 60s zonk pedals.

What paint did you use?

Awesome. Let's see some guys ASAP

Nice Johhny glad you're not using those knobs beautiful as they are we don't want any of that cool zonk labelling obscured now do we

Looking good

 

[Johnnyorange500]

Think I’m going for these knobs for the final build! What ya think?

 

[andare]

Not bad but I'd still like to see the OG knobs

What the original Cliff knobs?

 

[Feral Feline]

I like the knobs in post #11 better than the Cliffs.

Some appeal to the metal caps...

Sounds great!

Cheers buddy! Much appreciated. I’m Just glad it’s finished and it turned out well.

What did you use for transistors?

And why no gut shots?!

I've got a PPCB Zonk board in the backlog somewhere...

Looks killer! Do you remember the gain and leakage for each of the transistors?
