Ceriatone Forum

Hi everyone.

First time here. I've read many topics and find the support members give each other great. And precise!
I'm kindly asking for some of that support...

For my fist amp build, I'm looking at the Dizzy 30. Crazy, I know.
Since I'll mostly be playing at home VVR is a must.
Also, my budget is limited.
Last point: I live in Moscow. The DIY mentality runs strong in this part of the world, and with 15 million people you get suppliers and talent. But quality parts are a bit tougher to get by then, say, in France or Italy.

Being a complete beginner, I don't even know which questions should be asked first. I'll just fire away and hope some will actually make sense.

1) Does the VVR actually limit the maximum volume capacity of the amp? I kinda want to keep its ear-splitting ability intact...
If the VVR does limit the actual max output, is there a way to cancel the VVR? If I understand correctly, it is placed right after the power source, meaning it lessens all the voltage going in the amp. Is it switcheable in a way to give the amp back it's "integrity"?

2) Can I replace the EF86's with another tube model? I checked local supply and they can be qualitative, EXCEPT for the EFs. Ideally I'd want a pentode replacement which produces very similar response, but that doesn't break up every 6 months, or pick up the local Orthodox Choir FM station.

3) Grounding: I rent an apartment and cannot change plugs or electrical system. Not a single plug with ground. Now that is a risk I won't take. Is there a solution to this, testing and running a tube amp without grounded plugs?

4) Silly, but... On top of pliers, soldering kit and screwdrivers, which tools will I need?

5) How do I test the amp while building? Links to methods would do for the moment.

6) Plenty of radio interference where I live, and my main guitar has P90s. What are the common shielding techniques for complicated amps like the Dizzy?

7) I can barely read schematics. My physics classes are long forgotten. I'm not a complete moron so I'll use them and pictures of completed amps. How is Ceriatone's support (and patience) in dealing with noobs and really, really basic questions?

8) What the hell is a bright cap?

9) Is there a complete parts list somewhere?

That's it for now. All my thanks to everybody who posted all these informative posts (and pictures) on the forum!

I just finished a DZ30 and absolutely love it. Use the pics Nik has on the Dizzy 30 page at Ceriatone.com as you build. They are real helpful at understanding wire routing and whatnot. I had a few questions and Nik answered almost immediately through email.

For the build, definitely get a multimeter. One that has an audible continuity setting really helps. Use it to check continuity of your solder connections as you move along in the build. Make sure every grounding connection has continuity to the star ground and that every solder joint you make has continuity to the other end of the wire you just soldered.

As for EF86's there are a lot of suppliers in Russia with NOS RFT & Tesla tubes. These get pretty good reviews for ef86 tubes. Many nos ef86's are cheaper that new issue. (RFT, Tungsram, Tesla). I just purchased a boxed nos Amperex Holland Bugle Boy for $36 from an Ebay seller in the US. new production ef's are around $35.

Good luck and enjoy building your dream amp.  ;D

Indeed! Thank you so much for your answers. I'll also take your opinion in mind: checking out the Rock It etc.

I was away or a long time, but back and soon ready to start building an amp.

I'll look into that. Thank you!
