The other difference I noticed are C6 and C37 are on the board both electrolytic (they have been replaced with 10uf 450v) which I guess is incorrect as C37 on the schematic states 47uf 63v so again too many inconsistencies to be able to rely on any versions of the schematic. There are other proven factory differences between the board and the earliest schematics so for that side of things I think everything is fine. am I getting the right AC readings off the PT? If so, since the amp has obviously been tampered with in the past by someone else, did they solder the PT LV wires to the right lugs on the board? W9, W10 and W11 are the lugs used on the board but on the schematic these lugs are denominated W11, W12 and W13. So I replaced them but still the same readings. In my rig I use a Boss GT-8 with a Marshall JCM2000 DSL-50 amp. Get Wired: Four Cable Method Ahead of the Curve. On the other sides of D8 and D9 I'm getting around -58vDC and on the other side of D6,D7 I'm getting 0. Used as the Effects A return jack and Effects B return jack on the rear panel of the Marshall. #Marshall jcm 2000 dsl 50 schematic drawings pdfpdf (394964 bytes) GS37 37 Electronintorg T GS37 Explore Richard Dudleys. This is a scan of the schematics that was supplied with my kit. So tracking from the PT LV lugs I'm getting around 21vAC through to the rectifier diodes D6, D7, D8 and D9. Schematic for the S-5 Electronics K-12M Tube Amplifier.This is a scan of the schematics that was supplied with my kit. HT, heaters and bias voltage seem to be ok. I tried powering up the amp just to see if it was working at all.it does sound very flimsy and bad so powered off and proceeded to do some tests. I see now that the same designations appear on the 2 different pages. Schematics shown in BLUE are missing from the archive. Im not following the schematic that pompeiisneaks posted as being accurate. Anyways I'll state my findings, initial problem is that the channel switching doesn't work at all, the LED doesn't turn on either.so basically its stuck on the clean channel. Marshall, Schematics, Amps, Amplifiers, Tubes, Valves, Bluesbreaker, JTM-45, JTM-50, JTM-100, Major Series. Although lumped together as JCM2000 models the DSL and the TSL have. High 7's iirc.I have an early version of the DSL50 jcm2000 amp to which there is no reference anywhere.printed out the schematics I could find but there are too many differences in denomination of the components and wiring lugs. Marshall Amplification is a British company that designs and manufactures music amplifiers. Reading up on DC heater supplys, I am thinking maybe I have to remove one of the taps on the JTM60!ĮDIT: The heater voltage is high on my JTM60. I have a JTM60 that had a blown heater bridge rectifier when it was orphaned at my door. Perhaps the C1/C3 connection to chassis was a move to mitigate the heater bridge rectifier problems that were happening. Marshall Jcm 2000 Dsl 50 Schematic Design Deliverables Development, Marshall Amplification plc reserve the right to. Some of Marshall's earlier amps had a ground reference on both sides of the rectifier. JTM60 ( 3speakers)Schematic NAD - Marshall DSL50 JustPlayed a Big JCM2000 dsl sound. (Actually, you can spot this mistake in the Mesa Dual Rectifier and Carvin Legacy amps which foolishly use artifical centre taps on both sides of the rectifier, so maybe it's not such a beginner's error!)" It can be on either side of the rectifier the other side will received its reference through the rectifier. #Marshall jcm 2000 dsl 50 schematic drawings updateThis will short out the rectifier! Only one ground reference is required (centre tap, humdinger, elevation, whatever). PC GAME FIXES Command & Conquer Red Alert 2 for related No-CD & No-DVD Patch No-CD & No-DVD Patch troubleshooting: The most common problem getting a No-CD/No-DVD patch to work is ensuring that the No-CD/No-DVD patch matches youre game version, because the games exe is changed when a patch update is applied previous versions wont work. To quote Blencowe, "A common beginner's error is to try to add a ground reference on both sides of the rectifier.
