not a lot of choice, High prices caused by, most of the time, custom fees [ +27%]
So, impossible to find and try a Ceriatone, a Fuchs, a Caroll Ann, ... I don't talk about Bludotone, Glasswerk, ... ... Only some Two Rock and, of course lot of low price Fender, Marshall, ...
It becomes even difficult to find a PRS "Core" guitar !
Concerning components : we have some great shops. But not a lot about "NOS", so for your NOS Sylvania, Brimar, ... : you have to look in USA ( some in UK too ).
... but I've a little stock![]()
A Dumble clone has more components than amps typically recommended for beginners (tweed Champ etc.) but really is not so much more complicated. If you don't worry about trying to find Unobtainium NOS parts, then ordering components is straightforward. The building skills required are the same. It will just take more time to finish the Dumble, and the higher parts count will give you more chances to make a mistake.

Perhaps the HRM needs to be adjusted, how to do that is in the Dumble Files section here on Ampgarage, must be logged in to view.
I am attaching information on the various OTS models for you to understand how each model varies.

FYI, my computer gave me a pop up stating this download contained a virus.I am attaching information on the various OTS models for you to understand how each model varies
I ran it through a virus scanner online virustotal.com through 58 virus engines and none found any, sounds likely a false positive.

I got no answers or advices .
I know that I have to do MY OWN WORK and learn ( for example in this 118 pages forum !, etc. ... ) , do so some searches, ... ...
But, at least, to accelerate a little bit the procedure , May you help/answer me in these points ?
Some of you have probably work on these subjects on a Bluesmater HRM ... and every of you have ... begin to learn a day and probably have ask for some help, some advices, no ?!![]()
SO , Thanks![]()
--------------------------------------------------------------- Extract from my very long previous post ! ---------------------------------------------------------------------------------------------------
...
Also I will need a good multimeter (advice is welcome, in an average price range), some other measuring devices ? : there, again I will wait your advice (decade box, frequency generators, ... ???)
and also components more in connection with the "Dumble" style: resistances, capacities, ... (again, if you could advise me the minimum kit you must have!).
...
So what remains to be done on this head for now:
. the POWER OUTPUT seems low for a 50W ??? I can play at home with preamp volume at 6 and master at 7 !!! It didn't seem more powerful than my 20W Fuchs !!!
( I must admit that, until now, I didn't take any voltages measure : as soon as done, I will provide them to you )
...
. and set the bias to 38 mv : correct?
What Can I expect as voltage around the power tubes and PI and what could be wrong ?
. The Deep switch is wired upside down (not important) but I don't like the action = sounds muffled? : any mods around this deep switch in the BluesMaster ?
. the midboost is far too violent: I want a different setting (I even saw a three positions schematic here)
Do I have to "trick" around the 390pf cap in the mid switch or ???
. The PAB is way too much "violent" and I wish to tame it . : Where is the PAB resistor (I am lost without a schematic) ? is where to make mods or ???.
The OD with the HRM bypassed is more aggressive than smooth as on some Dumble (smooth and with a lot of sustain) BUT probably that it is logical with the Bluesmaster and its particular preamp and it will be hard to change !
some rubbers to smooth it or some filter somewhere ???
EDIT : of course, every componants change (these Holygrail for examples ? , basic mods, ..., ... which can improve immediatly this Ceriatone are obviously welcome![]()
