Building a Ceriatone Dizzy 30 (DC 30)

[Rotorcraft230]

Got a new kit to build. As always Nik promptly shipped the kit and I received it 4 days later. Wow 1/2 way around the world in 4 days, thanks Nik.

I’ve already started and here are some pics.

What happened to the image selector that was hosted here. Resizing the images is a pain.

Another delicious build, looking forward to more pictures!

 

[Rotorcraft230]

Thanks BlueX

I did make some upgrades.

F&T Electrolytics

Fender style indicator light

OT ohm selector switch.

Here is last nights work.

Screen and grid resistors.

Very nice, as usual. Hope she sounds great once finished. Not too soon though, I want to see more pics!

 

[Rotorcraft230]

Thanks, I’ll post all the way to the end with pics.

My son is gonna like it a lot. The EF86 circuit has some fuzz in it and he likes fuzz a lot.

Looking good man!

You know youre in for a treat when @Rotorcraft230 posts a build thread!

 

[Rotorcraft230]

Aw man, thanks.

Here is the unassailabled kit from Nik.

Worked on the ground buss, may not be the final design, still thinking about it.

I like the copper buss! Very nice. I'd leave it.

That's a straight copper wire

The buss material is nice, it’s copper and comes with the kit.

It’s the length I may change.

I usually use the earth wires that cones in thick solid electrical cables. Put it in the drill chuck, give it a few spins and comes out straight as an arrow.
Your work is always impeccable Mark!

I have a few tricks I use to get stuff straight and square.

Thanks for the compliment.

I did some readings on EF86 preamps after you posted this thread. I've got schematics for Vox AC-10 with EF86 in V1 position that I might build after my current project.

Do you know if there's anything in this DZ 30 layout/design to avoid the preamp to become microphonic (seems to be a risk with EF86)?

 

[Rotorcraft230]

Seems to be the tube. Nik sent an oring and rubber grommets for mounting the tube socket to the chassis. I can get closer pics when I get home to see how he had done it. For isolating vibrations from the EF86

Looking good.
I have a Vox derived project in embryo and am going to use a cascode preamp stage instead of an EF86 as I’ve had problems with 2 or 3 going microphonic on me (on my TMBEF86 18w that I built from Nik’s chassis and transformers) in use in a 1x12 combo.
