Re: THE HORROR!

Interesting. Didn't know it was so common.

I know I've read of this before, but like all things...if not practiced, gets relegated to the corners of memory. Never again. :)

THE HORROR!

Marshall JCM 2000 DSL 50, early version with the "crappy" PCB (which I've not had any trouble with...perhaps due to the 50w vs. 100w setup?). Anyway. Tinker tinker....replaced most (soon to be all) coupling caps in the .0047 to .1uf range with Sozo NextGen caps (nice), installed choke in place of re...

Re: Marshall JCM 2000 DSL 50 ... Sozo cap replacement help

Thanks Phil. I managed to fit it in...put some clear, PVC tubing on the end close to the switch, and angled the cap a bit. The rest fit just fine with one or two needing an altitude change to avoid hitting the other stuff (I hate PCB construction....sorry....). But yes, it fired up and worked withou...

Re: Marshall JCM 2000 DSL 50 ... Sozo cap replacement help

Awesome. Thanks. That's what I was thinking after making sense of the various boards and schematics....C30 on the "front board" schematic. It looks to be a tiny, white, square, .1uf cap, so that'll be a challenge to replace w/a Sozo. :)

Appreciate the help.

Re: Marshall JCM 2000 DSL 50 ... Sozo cap replacement help

Okay, how about this....I found out which 22uf caps I want to replace, but can't sort out which cap is the Presence cap.

Would any of you be so kind as to help?

I'm having a tough time sorting out the various schematics out there...appreciate the help.

Marshall JCM 2000 DSL 50 mods

Hi all, I came across a great deal on an older Marshall JCM 2000 DSL 50 head and am trying to make the best of it. It's yet to display the runaway bias drift issue, and other than having a noisy reverb circuit it sounds pretty good, especially with NOS Mullard, Telefunken, and RCA preamp tubes. I re...

Re: finished pictures JTM 45

Thanks man. Yeah, there's no shortage of options over here....but there's something about yours that I just like better. I'd cut the faceplate to not extend past the "internal" chassis, and I'd like to have both fuses externally accessible, but other than that, it's exactly what I'm looking for. I'l...

Re: finished pictures JTM 45

Very nice. Thanks. I do like their stuff, so I'm tempted to order some from them even though I wager shipping would be spendy. One last question: Does the faceplate hang past the ends of the chassis front? I was checking the dimensions and looking at your pictures and something wasn't adding up. Tha...

Re: finished pictures JTM 45

Super cool. Thanks. A couple of questions, if you don't mind:

1) Did you get the chassis from the same place as the faceplates, and if so, what's your take on the quality of both the chassis and faceplate?

2) Are those the new "NextGen" Sozo caps? If so, what's your take on those?

Thanks!

Re: finished pictures JTM 45

Looks great! Where did you get the white faceplates and the knobs?

Re: JTM-45 build recommendations

Thanks. I'd like to retain the option of running 5881s, while at the same time keeping the voltage high enough to do a KT66 right.

Re: JTM-45 build recommendations

Excellent...thank you.

I'm guessing a 320-0-320 PT would get me close to 410v on the plates of your average KT66 pair in a JTM-45, yes? I want to keep the voltages reasonable so I can run new production KT66s and 5881s without fear of meltdown...
