Guys take a look at this
http://cgi.ebay.com/Marshall-Plexi-Supe ... 500wt_1182" onclick="window.open(this.href);return false;
Whats the difference between the super100JH signature series and maybe a jtm45/100 or a 100watt 69 superlead

this amp is supposedly a JTM45/100 with the Dickinson specs. Never seen the inside of one, so I can't say if it lives up to an original.

I don't care for these amps personally. search and you'll find plenty of info on jimi, 45/100 and the 69 Superlead.

Is there documentation of the dickenson Amp, like all the values for the different parts?

there was a layout posted a while back, but a lot of the values were different from the photos that float around the net. I've got a set of those photos, I'll try to upload them soon.

it's a standard 45/100 but the 4 1ks are replaced with 470s, the 8k2 with a 10k, the 56k/250pf with 33k/500pf and the 16uf with a 32x32uf

the blue resistor near bias circuit is spot on with the dickinson ......but the rest ......well....... metal chassis , big can preamp cap , plastic transformers , weird power board ...... but it sounds good apparently though ...i just wonder about the long term reliability ( the only thing we don't know )

I can't talk for the JIMI but my JTM45/100 40th anniversary works great and has no problem to be compare to a metro...or a metro to be compare to it.
What kind of metropoulos do you compare to the JTM45/100. Did it use mustard or sozo. (If sozo what kind of sozo?)

I love the super 100JH after going to carbon comps and mustards.
540v B+ makes it a tube eater until you get the right glass,
they also seem to hate attenuators.
