Benjamin Fargen	Marshall models ??? To all: I want to become more familiar with some of the classic Marshall circuits. Can someone give me some insight into the classic Marshall models vs. their correct model # (I.E. Plexi = model 22??) A small list of the classics so I can reference the schematics would be great! Many thanks, Benjamin.

The basics are easy -

model 1986 is a 50W "bass" amp

model 1987 is the 50W lead aka "plexi"

model 1959 is the 100W version..

A 1986 differs from a 1987 by only a couple "bright" caps, and a few other little things..

a: tone stack (is a little different)

b: cathode circuit of the 1st stage (is seperated)

The 1986 is quite close to the 5F6-A in its basic overall layout. (put 'em side to side..)

Those are the "classics" anyhow; they'll take you up to teh early 70's. Someone else can pick up the thread from there..

Benjamin Fargen	Speed, Thanks for the list! Have you ever built anything like the 20 watt 2 X EL84 Marshall tremolo amps? They look kind of interesting........never seen one in person though. Benjamin

SpeedRacer	Yeah, not the trem version, but the regular one. It's a screamer. Highly reccomended!

Trace	Speed; I don't think there's anything to pick up on my man. You nailed it down pretty well! You devil you! Trace

Cono	Hey, you guys, What about the 2203/2204 master volume heads?? Also, the 1962 Bluesbreaker/JTM45 circuit? Those are classics, no? just my $.02 Cono

absolutely.. I didn't mean to diss anyone's favorite amp head there! Just put those in as a starting point..

Actually for anyone that's into all things Marshall, you coud do a lot worse than buying "Marshall: The History of Rock".. lots of great archive pics, Steve Melkisethian odds & ends (tube info, ads, etc) and a heap o'schematics including a JTM 45 Schem with notes from Ken Bran on which caps go where for which model. Cool beans says me.
