I'm new onboard. Trying to decide between JTM45 or the Plexi head kits.
Ultimately I'll be going for the humbucker / LP sound but I do want amp versatility so that my Tele's also get their just rewards. Lets say both early Keef '69-72 and ZZ's Billy G.
This You tube demo kind of says it all.
I'm guessing it's the sIII Plexi that I'm after.You opinions much appreciated.
Thank you. BP

18W will be a lot easier to manage/play and build.

JTM45 are damn loud

Got it! lol. Now which 18 W Trinity amp head kit do I order ?
By the way I just noticed that no tubes are included in the price!!
So now I also need to know what tubes to get in order to get that Plexi tone.
Jeez if Trinity is building basically a Plexi amp one hopes tube recommendations are available?

Hey dude, I really recommended the trinity 18w plexi kit. I got the V6 version with VRM add-on. Totally stoked, nails the plexi sound, dynamic & cleaner at lower levels, and when cranked, those syrupy fat lead tones. My main axe is kinda Les Paulish, I play Lollar Imperials as pickups. Highly recommended. Cheers

Also I used JJ tubes throughout the amp. There's various demos on the forum, I made some too. Have a listen

Thanks Corey. Why did you chose the 6v6's? I thought EL84's would be the natural selection for Vintage Marshall tone ?
Who advised you on what tubes to get? I mean I presume it's VI,2,&3 plus the 2 power tubes.?
I'll look for those clips of which you speak.

The sIII and Plexi are easy to swap back and forth. Get the kit you think you want the most and you can always convert it to the other pretty easily.

But yeah, I recommend the VRM too. 18 watts is louder than you might think.

As far as EL84 vs 6V6... in my opinion, the 6V6 is better than the EL84 in every way. Has a much better bottom-end for that extra "fatness" and the mids are not so in-your-face. But hey, that's just the way I feel, you might be opposite. The V6 18-watt kit has both and they are switchable.....

Marshall used EL84's for economic reasons, nothing more. At that time, 6v6 tubes were only made in the USA and were too expensive to import. Mullard (in England) made the EL84 to be "like" a 6V6 and were readily available to him. Same with 6L6 vs EL34 tubes.

For a JTM45 tone 6V6 will be a bit fuller and provide a rounder tone.

I'd go for 6V6 in a sIII or Plexi 18W.

Thanks for the input fellas. Very interesting your ideas on the 6V6's over the EL 84's.
Yes I indeed was considering the power scaling feature.

There's not much in it between 6V6 and EL84, I'd be happy with either. My amp has both however, so I can compare... That's what you get with the 'V6' version of the kit.

I use it a lot at church now, using the VRM set at half power. I would say the 6V6s sound better at lower power on those starved voltages, and are nicer when clean... But the EL84 have the slight edge when the amp is dimed on full power. YMMV

All the best with your build, be sure to post some pics when you're done :)

You can always consider 6CM6s in this application. Read this post http://www.trinityamps.com/phpbb/viewto ... 94&start=0
