JTM45's might be the perfect single channel amps...

I was once told that Duane used two fifties daisy chained, but they were the bass models, not the lead model plexis. Richard was reported using a single 100 watt plexi head. I do know that Richard reported using mostly the 100 watt models, and playing with the bias settings, in several interviews.

Too bad you didn't get to try the 45 with KT's, because in my opinion they are much more ballsy than regular 6L6 types.


I has KT-66 in it which happen to be my favorite output tubes.

BTW - KT-66 uses 1.3 amps in the heater circuit as opposed to 0.9 in 6L6 tubes and the KT-66 tubes need to be separated by 3.5 inches per GEC's spec sheet.

Iwas originally told the same thing about the KT's not fitting, but laterbegan to doubt that because i don't recall ever seeing a "large box" 45. I intially tried to find some NOS 6L6/5881 tubes locally, but never followed up. I am kicking myself because an earlier JTM45 RI went for around $650 a couple of weeks ago on Ebay. Could have swapped out the PCB for one of the Metropolous handwired boards and i would have been in tall cotton for less cabbage than a HW'ed clone would cost me....or even a kit possibly.
 
Re: JTM45's might be the perfect single channel amps...

I think someone here bought that 650 one.

On the KT66 fitting, with this cherry head the clearance is kinda tight. Just enough room with the Groove Tube versions (they are tall) to come out, but you have to be careful not to pop the top glass too hard. But, I got some tube sockets that mounted up from the inside of the chassis so that the top of the socket (where the tube goes in) sits pretty flush to the chassis. So, it works.

But, if you had trouble still, it's only 4 bolts on the bottom to take out the chassis. Easy access on the insides to get to the nuts. No issues.

Thanks Larry, I enjoyed the coffee and the playing.

1) EJ Strat running Sweet through a 2X12 open cabinet at 16 ohms.
2) My Warmoth body/ USA Custom neck stratocaster that uses SD-JB, Little 59 & Phat Cat with EMG modified tone and boost through the 4X12 cabinet at 8 ohms
3) 59 Les Paul running bitch through a Marshall 1960 cabinet with original celestions.

Looks like Scott might have to give up his realtors gig and start making more of these heads (PS Scott I told them about the Franklin)

I will be posting clips later, if Scott can agree with my poor playing capabilities.
Yeah man....My favorite EASILY is a Strat running SWEET thru the open-backed 2x12 with the 12H30/Greenback combo.

Rock on Stratman.....enjoy that bad boy:beerchug:

Scott.........might wanna start teaching your son the amp business:wink:
 
Re: JTM45's might be the perfect single channel amps...

I really have to laugh a bit. The jtm45 thing was a simple request from Armotron. I'd never built one, never really played one to any extent. I'm glad you guys are liking them. I like them as well I am finding. The good news is that I've had several to "test" lately. It's difficult letting them go, but I get to push them for a while, then they leave. It never gets stale at this point.

The funny thing is... in my personal opinion, the Franklin smokes the Edana on many different levels. And, I've yet to sell one of them! :)

Just goes to show you. That's okay, the cathode biased class A sister to Edana is about to be born. Trannies are on the way. :)

HAHAHAHAHAHA


Actually, I've always wanted a JTM45. When I stumbled upon a deal for a Bluesbreaker RI, I thought I'd love it.

It sounded great when you played it but it hummed relentlessly....very loud amp.

So when you started things up, I knew I couldn't pass it up & as it turns out, it was & is the amp I wanted from the start.

As for the Franklin.....I'd love to have one but the MRS. would literally kill me:D
 
Re: JTM45's might be the perfect single channel amps...

Well, terry, dead customers seldom buy more amps. So, keep the MRS happy. Buy her a diamond or something. It's the tit for tat law of marraige. You give her a toy, you get a toy. :)

I have a Matchless Clubman that i've not even opened up yet, but it hums pretty loudly as well. It's probably just a bad tube somewhere. I've not had the time to mess with it. Now that 007 has left the building, it's the only amp I have in the shop. So, when I get back from my trip this week, I'll probably throw some new preamp tubes in.
 
Re: JTM45's might be the perfect single channel amps...

I knew a guy that was married to a rather wealthy trustfund woman. She wanted a litter of kids. He really didn't. So, she'd buy him a truck or something in order to get him to agree to knock her up. True story.

After 6 kids they divorced and he's dirt poor and one of the worst excuses for a father I've ever seen.

so, modify the tit for tat rule to not include human life.

That's what I'm hoping for. That among several other things. I'm also hoping for sweet semi-overdriven tones. That partial breakup sound is to die for in a good NMV amp.
 
Re: JTM45's might be the perfect single channel amps...

HAHAHAHAHAHAHA......VERY FUNNY!


Yeah, might be a problem with a tube because my Clubman was pretty quiet!

your cherry head is ordered and on the way. handle is not being attached so I can stick that leather/gold gibson one on there for you. cream faceplate and backplates are ordered as well as the oxblood chickenheads.

I've got to finish evans amp first, but as soon as that is done, yours won't take too long.
 
Re: JTM45's might be the perfect single channel amps...

You rawk man! Glad to hear the news of the parts on order. Should be stunning visually as well as audibly.
 
Re: JTM45's might be the perfect single channel amps...

These sound pretty darn good. As time goes on, I'm leaning more and more towards vintage tones/gear.

Still love the Mesa though. Killer scooped mid cleans for single coil playin and great distortion for some hard rock, balls to the walls.

Do you guys think a JTM45 has more head room than a JMP 50 watter?
 
Re: JTM45's might be the perfect single channel amps...

OK - Playing on 2 it's very loud and clean with gobbles of substain and chime.

Played Jimi and SRV tunes for about two hours (Still on 2) and only stopped because my ears started to ring.

6 neighbors stood around drinking beer and making song request, that included a 61 year old, who requested some Hendrix, which suprised everyone. Turns out that guy is an old guitar slinger himself and plays a pretty mean guitar (Even if it is an old KAY)

Got a lot of clips, which I promise to post soon on clips.

Scott and Jeff, I may just retire Little Jimi for special only status...

Oh yea, played it throught an old Fender Vibrotone coupled to 2X12 Open back Jensens just for the heck of it, and it is evident that it sounds good no matter set up your playing through. (Wait until you hear Little Wing and Layla in this particular set-up)
 
Re: JTM45's might be the perfect single channel amps...

JTMs are really cool amps... but theres something about the herculean dynamics and Girth of a 2203/2204 that makes them sound "small" IMO

I can under stand that. The master volume on the 800 allows you to have a fuller sound at lower levels IMO. Both are great amps Also I think the 2204 has 10-15 more watts than the JTM even if they say it is 45watts.
 
Re: JTM45's might be the perfect single channel amps...

Didn´t think about the MV point, but that´s possibly part of the reason... though I don´t know if any of these volumes can be considered "low"... all of them will blow your eardrums out your nose if not careful /protected ;)
 
Re: JTM45's might be the perfect single channel amps...

any of the good amps with SS rectifiers are going to have more juice than one with a tube.......headroom, baby:naughty: That is what sag is all about. Power section gets hit with a really big transient and can't keep up. Not so much of a problem with SS circuits. You should see the size of some of the mega-dollar tube stereo amps. (big ones in the 300-600w per channel range) I have seen some that have so many power tubes......big monsters, mind you, like 6550's or KT88's.....that they look like a set from Forbidden Planet and will raise the temperature of a LARGE listening room by a few degrees. That is what it takes to push low bass through speakers whose impedance can drop below 2 ohms on low notes without farting out like the neighbor kid's car stereo blasting Dr Dre......you kow what i mean:bigeyes: It is a trade off.......you can have cascading preamp scream or nasty power amp sag, but getting both AND having them both good is a tough job.
