    What do I have in here? (JTM45 content)

    I just was inspired to check out whats going on at the Forum because of Ramheads clips I just listened on youtube, pretty much as good as it gets playing and tone wise ! So, now I too will have to read the entire thread from the start :hbang: That will have to wait until I fire up the 68 100...
  2. JTM 100 Mk V

    Anyone knowing what are those choke models and what are their differences ?

    To me the main concern is how they are different in terms of construction and tone. This is a power supply smoothing component or soothing component as I like to think. So to be simple, a smaller unit could sag in your power supply rail where as a larger unit could provide more firmness. Just...

    Electrolytic Caps For The Ol' Dogs : Where are we at ?

    Super Cool Responses. I would buy the Daly/Kermet based on reputation alone and give them a shot. My current Amp is a very rare example of filtering, layout and transformers. What I find remarkable is the places that make each amp a gateway to good vs. not AS good. It could be one part. Add...

    Electrolytic Caps For The Ol' Dogs : Where are we at ?

    Cool Beans Frens, Thanx for the feeders and nice intel. I will shurely take your advice and report back. These few heads are real quilrky with the parts. I'd be a knostic (Sp) on that one, but I get results with the stock parts that are epic. Stock, perfect tone. Try to replace a part and no no...

    Electrolytic Caps For The Ol' Dogs : Where are we at ?

    Ol' Dog here. Die hard pre pcb. Did alot of research covering the old and now gone. Have a bit of experience with the new and at this point I'm seeking some consensus among the collectors and techs and the Pleximaster ;-) Mallory is gone and we now have CE, I've had good luck with them. F&T has...

    Jose mod '69 Super Lead

    This listing caught my eye when it came out as well. I'm familiar with the Outlaws and like their music so this is a legitimate pedigree. In addition since the listing, JOSE mods have gotten alot of further understanding as the various mods surface and are analyzed. Jose was solving problems and...

    68' SuperBass Lost Its Mojo : Marcon 40-40 PI Goes Bye Bye. . .

    The reason I got in here to post this whole experience is that my Marshall was 'boxed' or what you would call so perfect that you would not toucn anything. That means no screw touched or anything changed like a MLB pitcher that practiced stupid supersticious behaviour. I was that rediculous with...

    Jimi Hendrix 1967 Monterey

    Clip below for Hey Joe: So recently my 67 Plexi went down because of noise and a failing Phase Inverter Cap. I posted on the LTV about it and its ongoing as I shake it down with a replacement. It sounds amazing and the new part brought out some new tones and took me to Hendrix. I've never been a...

    68' SuperBass Lost Its Mojo : Marcon 40-40 PI Goes Bye Bye. . .

    Ok, back from shakedown round two. I decided to simply lift one half of the F & T so I went from 32 / 32 down to a single 32. Before I did so I measured the value again and they are at 36 each side 72 total. So same circumstances and recorded again to listen back. In the room I felt a bit more...

    68' SuperBass Lost Its Mojo : Marcon 40-40 PI Goes Bye Bye. . .

    Ok, sorry for the delay on the update. I decided to not trust my first impressions, dug up an old recording and decided to set up for a comparison. Before I did this however, I had literally no burn in time with this cap so I took it to jam and brought a tube screamer and wah. The first thing...

    68' SuperBass Lost Its Mojo : Marcon 40-40 PI Goes Bye Bye. . .

    Thanks for the insight. Thats the situation I'm in exactly. The whole amp is stock so this day was invevitable. I still have the Hunts 100/100 and the Daly 32's. So I guess next question would be regarding favored replacement brand. I've got Sprauge on hand and would Guess F & T would...

    68' SuperBass Lost Its Mojo : Marcon 40-40 PI Goes Bye Bye. . .

    Greetings From Toneville everybody , Well my beloved 68 SuperBass developed some noise and an overtone that was ugly, so I shut it down and put it on the bench. I immediately noticed a bulge in the PI cap. I've been pushing my luck on the...

    Ol' Marshalls Never Die . . .

    They Keep Sounding Better n Better. GOOD DAY! All, Pleximaster sent me. Actually, been lurking for a bit, just getting around to posting and a hot soldering iron. I've been playing 67-71 50 & 100 watters with origional cabs and speakers ever since I plugged in. I like the NMV wide open roll...
