I whipped up a vero for the ROG Ruby amp tonight - thought i might give it a go, though it's maybe not as compact as i could be. It sounds pretty nice, and is supposed to go in a cardboard box along with a speaker i salvaged from an old tv I built mine with a 2N5457. J201's work fine as well.
Here's the vero - verified and all...

Thanks I may give it a go. I have two tinny speakers saved from my old, crashed mac. It will sound geeky with those speakers, but hell... why not

I decided that i liked this one enough to try and compact the layout a bit. It's not verified yet, but should be accurate Here you go:

Which ohm speakers can you connect to this ?

Here is my (VERIFIED) version of the one knob Bassman modded Ruby Amp
Sorry for the lots of jumpers and the jumper crossing. I really wanted to make it as small as possible.
Fits nicely in a 1590A
I built this last week and used a 8ohm 12" 70W speaker for it. It sounds okay to me.
First post BTW (thank you for all the knowledge here).

Just a suggestion : put a 1 watts resistor of 1/4 the impedance of your speaker, in series in the output.

Q: Is there any advantage to using solder with a 2% silver content?
A: Yes. Silver solder keeps werewolves away from your amp.

kleuck, I'll try it on the weekend. What does this exactly do?kleuck wrote:Just a suggestion : put a 1 watts resistor of 1/4 the impedance of your speaker, in series in the output.
For those who are interested pics of my build:

I don't want to spoil, it's an experiment, i hear a big difference, want to know if someone else hears the same.
I tried with a true guitar cab (and that's the point...somewhat) so if anybody is willing to make the resistor switchable (just short it) and test with a good cab....
Actually i used a LM380, but doesn't matter.
Tiny built
I make a buffer in this enclosure :

Allright then, I still have a free DPDT switch next to my pot. That was used to switch the 220pF cap on the volume lug but I didn't notice any difference so I finally left out entirely.
Anyways I breadboarded the original two knob Ruby and this 'Bassman' modded one and liked the later better with my Strat. Still somewhat sterile but I don't expect too much from such a low cost low part count build. Btw I drived a real 12" guitar cab with it. Plenty of volume for apartment practice.
Nice brushed enclosure kleuck. Love it.

Well, not really brushed...

That buffer looks good! I'm gonna try the resistor trick as wellkleuck wrote:I don't want to spoil, it's an experiment, i hear a big difference, want to know if someone else hears the same.

Thanks guys ! Hope you will hear something interesting (BTW, a 1/4 watts should be fine actually, i used a 1 watt one as the LM380 is a 2 watts IC, not useful with a 386)

I'm going to be honest. I didn't.kleuck wrote:So, did you hear something ?
I ran it through my 12" 70W guitar speaker 1x12 cab but no noticeable difference for me with or without the resistor.

Shit, anyway i used a 1 ohms for a 3 ohms speaker, more obvious result i suppose, i'm gonna make a little TBA820M amp and give it a try with different resistors.
