DIY Valve Guitar Amp Head

[DrNomis_44]

Just read elsewhere that this amp build is to be based on a SLO-100... Is this true?... Do you have a circuit ?... Are you going to include clean/crunch to OD switching via a foot pedal ? ...

Yep, I've got the complete SLO 100 circuit, which includes the full two-channel preamp, power amp, power supply and footswitching circuitry, I got it as a pdf from the Sloclone.com website, and I'm going to be implementing the full footswitching system in my amp build too.


The only thing I'm going to be doing different is switching to EL34 power tubes, the circuit specifies 6L6 power tubes, so I'll probably get more of a British high-gain sound out of the amp.

And rather than use a set of four power tubes, I'm only going to be using two power tubes, there's a Triode/Pentode switch on the back panel of the amp which was something I added to the amp in a previous build, the Triode/Pentode switch basically re-configures the power tubes so that they can work either as Triodes, or Pentodes, the output-power drops to around half-power in Triode mode but that also changes the feel of the amp too, I thought it was cool enough to keep.


Interestingly enough, the SLO 100 footswitching circuitry included in the pdf is pretty simple, based on LDR/Led opto-isolators.


If you're interested in a copy of the pdf, here's where I downloaded it from:
