Mine is noisier, but the big difference is that the drive has a bit of a fuzzier sound rather than the tighter overdrive on the original. Almost has that 'splatty'/gated sound when I roll back the gain to around 50-75%. It sounds better with the gain maxed, but not as good as the original.

Do the transistors do much in this circuit? I measured the voltage and it seems like the clone is taking in slightly higher readings than the original.
Mmmm check you build a little more, I made several units and all sounded the same as the original, on low and high gain settings.
which schema are you using? please share

Mmmmm arrhh.... first post of the topic....

So how long do you think is it going to take for Joyo to clone one based on your schematics?

I'm guessing you guys know that michael_ibrahim is the genius behind MI Audio and MI Amplification.... or am I just being a douche for bringing it up?!

Additional guts from my friend Ron, maybe can help some small differences.

I drew up a vero for the 6 knob Tube Zone using the first schematic posted, but made the correction for the last transistor's output. I built it up and it sounds awesome with a bass.
if you use low enough profile 100u caps (like I did), even with the stacked A50K drive pot, it'll easily fit in a 1590B.

here's the vero:

and here's a pic of my built and tested board:

Damn! You got that in a B enclosure!
That's it. I'm building one that small.

Well done. Looks great. I'm thinking of putting the old girl back into production. I do miss the old Tubey

Hey Michael, now you've discontinued it what's the chances of you sharing the Blue Boy Deluxe schematic? :mrgreen:

what schematic you used?? i tested it in breadboard but it squels on high gain setting..any mods to eliminate the squelling??

good day everybody..

my clone tube zone still squeelling when i turned up the gain to 12..what is the problem on it i check all the parts theres no problem..
what cause this squeeling??

any advice??
