It's not terrible, but there are better, more accurate layouts posted here.

Welcome to the ampgarage.

I think originally the Ceriatone D amps were based on #124 which was disclosed here.

thanks,
i'm looking for a new project,i've already built a preamp based on the 1977 schematics (find on this forum)
which one could be good(in dumble one's of course) ?

Not sure what the 1977 amp is but there is of course the later generation ODS, HRM, the Bluesmaster, the earlier classic ODS.

[alexso]

i don't know too

it's a schematic i've found on the 5th page name 1977 shematics;

can you oriented me to a good ODS ?

Thanks a lot

Alex

[Structo]

Sure, if you follow these values, it should get you in the ballpark.

[alexso]

waouh, good,
i'll keep you informed

regards

alex

[alexso]

have you made a layout ?

Edit :
sorry i've found it !

[alexso]

a last questions sorry !

what are the values in B4 and B5 with and without tube

Thanks a lot

[Structo]

That depends on what power transformer you end up using.

Ideally you want about 190v on V1, 200v on V2 and 290-300v on V3.

You should adjust your B+ voltages for the proper plate voltages at the tubes by altering the dropping resistors on the filter board.

Isn't the ODS50 layout from Ceriatone very much like a Dumble. If you want to tweak it with different values etc thats another thing.
What board do you all use if not the Ceriatone?

[Structo]

Most if not all make their own.

[johan]

That may be but isn't the Ceriatone very much like a real Dumble.
No Dumbles are 100% the same but are the Ceriatone "wrong" in any way? Seriously, I'm interested. May need a new board for an old Fender I'm thinking of giving a "makeover"

I think it's safe to say Ceriatone layout is very close to the real thing... Nik uses a few different values here and there but you could change those easily if you wish.
