Dixieman	1970 Marshall SLP 1959 I recently acquired a 1970 Marshall SLP that has been severely butchered over the years and I was wondering if anyone might have a photo of the chassis layout from a stock Plexi showing the circuit board, as I'm not quite sure of the original component layout, so I can bring this baby back to its original specs!

nek	Check out this page. The subjects are 50W. I am sure you can generalize. Good Luck. Have Fun. http://www.obsoleteelectronics.com/Marshall_Tech/marshall_tech.htm

Jim S.	AFAIK, Marshall switched from Plexiglass control panels to brushed aluminum sometime during 1969. My guess is that your amp was made before 1970. Is there a clear date code on your amp?

Peter S	Jim is correct......a 69 Marshall could have the Plexi panel or ali......after that it's all anodised aluminum. PS

Tonefactor	Also, Marshall did not have an SLP model until recently when the reissue 100 watt Plexi came out. The original 60's and 70's 100 watters were called SL's (aka. Super Leads).

Joe L	I found these pics on ebay for a plexi that was for sale. They are the clearest plexi pics I've found. http://www.ccxus.com/~jlemoine/JTM-45%20Preamp.jpg http://www.ccxus.com/~jlemoine/JTM-45%20PI.jpg ..Joe L

Rebel420	Anyone else notice on this JTM45, that the cathodes on V1 are split? although, the wiring looks a bit heavier than most, so it could be modded. very good pic tho of the chassis!
