5 watt SLO

[Rev D]

 Sorry if this should have been in the sound clip area, but its not my amp and I was more interested in people hearing how heavy this amp sounded.

 Perhaps this thing has been posted here before and maybe the builder is even on here, but I ran across this on another forum which linked me to the source of this clip. I actually had to send the builder kudo's because of how big this thing sounded. It uses EL91 as output tubes.

 It was rather funny as I had my headphones on from listening to something and I clicked on his sound clip link and wasn't ready for such a beefy sound to come jumping out. I literally jumped before looking for the volume to turn it down.

 This isn't my style of amp, but it does have 4 or 5 channels and some of them really offer up some good classic rock tones. Anyway just thought I'd share, if you've heard it before sorry I wasn't sure if its been seen by everyone yet:

That does sound pretty chunky!

I've been playing around with EL91's for the last year or two.  I've got a single ended amp that delivers just over a watt and a push-pull amp that does around 4W.  Uses the same transformer - Hammond 125C - as in that SLO clone.  Seems to be a good combination.  Mine has only two triode stages before LTP and so way less gain than him and hence lots of output stage distortion.  Perfect for blues/rock sounds.

EL91's are fairly plentiful and cheap.  They were used by the military here (UK) so lots of mil stamped (e.g. M8082, CV4063) but Mullard made and branded surplus around.  They sound like their bigger pentode brothers but quieter and to me better than using triodes for low power output, e.g. ECC82, 12BH7 etc.
