    I remember seeing the adds in Guitar Player magazine back when they first started reissuing them....and I didn't know squat about much of anything except they looked cool as fudge, and I wanted one. I think I was playing a peavey renown at the time. Time went by, and I just never ended up getting one.

    Owned all sorts of Fenders, had a Marshall dsl 50 for a short period of time, and now days I have a couple of Dr Z's that I really like.

    Any way, about a week ago I got a really good deal on a used 1960tv cabinet. Ended up selling one of my DrZ's and saw this JTM on Reverb for what seemed like a really good price compared to a new one, so I jumped on it. Between the amp and cab I have 1650$ bucks invested. I was a little apprehensive about how it might be contructed, I knew it was pcb, but could not find any current pictures of the guts of a newer one compared to some of the first reissues. Well, I was pleased to see that the pots and tube sockets were all chassi mounted with flying leads. Appparently mine was wired by Anita and Julie...ohhh la la.

    I've found a site that speaciallizes in good simple mods, to help improve upon the reissues, so I may give that a shot later down the road, but otherwize...I think it sounds pretty darn good. and I still think they look cool as fudge!!!!!![​IMG]

    Goddang, that was a good band! Aside from Ronnie Wood and Rod Stewart, those guys were tiny.

    Congrats Hoff!

    I have 3 of the JTMRI family: a 2001 45 which got stuffed into an 18 watt combo shell, a 2003 45 head that got moved to a mini head and a 1998 Bluesbreaker with UK Greenbacks. They're fantastic amps.

    Most folks complain that they don't sound like the Beano amp or a true vintage JTM45. That's true. Where this amp excels is as a clean platform for pedals. IMHO, the reissue is more like a JMP50 (1987) with 6L6s and a tube rectifier. I use mine with a Barber Direct Drive and an AC Booster. I can get any tones I need and they rock with my Tele and Les Paul.

    For me, there's no need to mod them beyond replacing the stock Sovteks with something decent. I like Tung Sol pre's and TAD short bottles for the power. That's an affordable pairing that sounds great.

    Here's a pic of my re-housed head to give you an idea of how I like to run them. Enjoy...

    I also have a 1960TV cab. They're fantastic. Can't wait to hear my future JTM45 with it.

    In the meantime, it's paired with a SuperLead and the sound is glorious.

    thanks fella's, I switched out the stock marhsall 5581's for some tunsol 6l6's I had, think it made it just a lil bit smoother.....tried to bias in some kt66's, but couldn't get the range down low enough, gonna take a lil resistor swappin to accomplish those

    Those amps run about 400-410vdc, depending on the rectifier you're using. The 6L6 and KT66 tubes you're talking about are both 30 watt tubes. If you bias them at 60% you'll be in the low 40mA range (depending on exact plate voltage). You really shouldn't need to mess with resistors - either tube should bias right up and easily handle that current and be within the sweep of the VR1 bias pot.

    Let us know how it goes.

    thanks, Stormin........my kt's I think were in the high 40's, even with the bias pot turned all the way down, I didn't want to take a chance or monkey with it tooo much just yet, doing alot of reading and research still
