Re: Amp Build: Ceriatone Kraken 50
All done!
Just doing some testing now. I'm using a 47K 5W pot wired as a variable dropping resistor. This way, I just clip it to the filter cap and I can tune all the voltages in the amp. Typical value is 10K. I set it to 18K, which is what the Yeti uses (higher voltages). And my B+ is a whopping 515vdc! That's without power tubes though. Once I stick some in, it'll probably come down a bit. I don't really have a set goal in mind. But I'll play it with a few of the resistor values I have on hand and figure out which one to use.
I also got some new Tefzel hookup wire in some fancy colors for the next build. And I'm going to try to make the lead dress a little better next time around. I wanted to get this one done so I can start testing a few things first, tone wise.
Current voltages with no power tubes and 18K dropping resistor:
MAINS: 124.4VAC

Re: Amp Build: Ceriatone Kraken 50
Here's a clip. This is with a 10K dropping resistor. Probably my favorite value so far. The volume is as loud as I can get it without clipping the mic on my laptop, sorry lol. I'm working to upload the other clips with different voltages too. But it takes a long time for YT to process 'em. I'm still toying with a few parts here and there.
Voltages in this clip are:
MAINS: 123VAC
AC FILAMENTS: 3.33
DC FILAMENTS: 6.0

New clips. Made a few other changes. I think it sounds much better now. Just trying to decide on a slope resistor.

Re: Amp Build: Ceriatone Kraken 50
Great looking build! What kind of resistors and pots have you got in that Solano build (which looks awesome as well!)
Not really
Re: Amp Build: Ceriatone Kraken 50
I'm just going to send customers photos of your amps and then tell them this is what is under the hood of your amp so no need to remove the chassis from the cabinet.
They will of course receive my substandard bastardization construction method of amplifier building.
Good name for an amp as well Kraken!

The SLO Clone I built a few years ago? I used whatever the real SLO has. I forgot exactly. I think PEC pots and Vishay CCF60 resistors.

Re: Amp Build: Ceriatone Kraken 50
Deep slope is my fave. Bet 47k even better. We have a litte gain to burn!
Great amps from you, always. Very nice!

Signatures have a 255 character limit that I could abuse, but I am not Cecil B. DeMille.

This thread is old, though. I think my more recent build sounds better.

Hi.
Nice looking build.
So where do you source the PRP resistors?
I haven't found a distributor around these parts.
