Wow, I finally started this thing tonight... got my turret board done, and went over all my parts. Of course I was short one resistor.. doh.

WIll try and get this thing going soon. Hard to believe its been a year nearly since I started gathering parts for this. I am embarassed!

Well, I finished the amp tonight... and as I generally do - going against all logical processes - I plug her in, and flip the switch. All tubes are glowing, nothing smells like its burning, and there is volume, but very low (in either side of the amp)... so I know something is not right.

Par for the course for me is to leave out one ground, or jumper, etc. Will go through the wiring tomorrow and check it over...

Back soon with good news I hope

AJC

Often that kind of symptom turns out to be a wrong resistor value in the PI.

Anyway, first check your voltages and compare against the voltage chart for Trem amps in the Downloads section on 18watt.com

Nope, it was......... (drum roll please) A missing ground wire!!

I am notorious for omitting ONE ground in almost every amp I have built so far. So thats what I expected and it was the case. Just took me 10 minutes to find it, solder it in and try her out again... SUCCESS!!!

Just played it for an hour... with three different guitars. SOunds great, the trem is wild! Lots of options for sure. I love it!

Thanks again Stephen for the awesome cabinet.

Looks awesome! I'm a real sucker for those Bluesbreaker style combos.

Any chance of some focused pictures?

Sorry those were with my Blackberry. I just got my Canon lenses back from a friend I lent them to. Will take some pic tomorrow and post.

I was playing the amp tonight, after dinner, with a few more guitars. Funny how it always sounds best with the guitar you are most comfortable with One of my older home made jobs, which currently has Seymour Duncan P-rails in it... the amp sounds killer!

I am loving this combo...

AJC

here you go...

Your camera really brings out the textures in that carpeting.

Oh yeah, your amp looks nice too!

Yeah, sweet berber.



And the amp is even sweeter. NICE!

I modded the normal channel's inputs on Zaphod's advice and now its even sweeter

I love this thing.. really!

This amp sounds so sweet... and it has two destinct voices, on the normal and trem channels. The trem I found a little more "intense" even on the lowest setting, and I tried a few different 12AX7 tubes in V3, it does change things but I like the tone from the Tung sol tubes. Just going to leave it as is I think.

That is the Normal Chanel in the sIII BTW!

What's the input mod from mr. zaphod??

I love the tone of the normal channel sIII. I find with my guitars I almost always have the tone pot to the left though (say around 9 oclock). I might want to tinker with it and take off a tad bit more of the treble.

It only works in a classic/trem 18W or 18W Lite II, where you have two Normal channels. The mod makes it so the "Hi" input jack gives you both input triodes in parallel, for a thicker sound with a touch more gain, and the "Lo" input just gives the regular single channel. I think Mark Huss may have been originally responsible for this mod.


You can play around a bit with values of the caps on each side of the tone control pot.

I'm building the amp in ltspice right now so I can figure out what I want to try out before I start swapping out caps.
