Hi there guys,

I've been looking at both the JTM1 and JTM145 for a while and i'm gathering the bits to do a build. As for now I've set my eyes on a PT that does faccilitate 200V and 6.3v

Is there anyone that has an acurate PTP layout out this point? Preferably for the JTM145
Also I've seen some schematics wich seem to run heaters in series on 12V has anyone done one on 6.3 paralell?

I'ts such a cool amp so I really want to do this one nicely!

I'd love to hear from you. Also, special thanks to everyone who has been studying this amp to come up with all the info!

What about the one on the second page?

I know it's an old post but I hope somebody will be able to help me. It's my first build, I've been reading a lot lately (I have a lot of time with that bloody virus ). Can someone share with me the wiring of the OT. On the JTM-1 (or HTM-1) It's the Hammond 125A. Which pin did you choose? for 8Ω and 16Ω and how did you wire it?
Thanks

I cannot seem to find a layout for the JTM145, anyone made one? I dont feel competent enough to make a decent one from the JTM1 versions that have been posted, all help would be appreciated!

Sorry for joining this discussion way late in the game but I am looking for a schematic to the JMP-1H/C. Does anyone know what the model is that is posted on page 27 of this thread? It says it is a “classic 1 watt” but there is no amp by that name produced by Marshall as far as I know. It looks really close to Matec's JCM-1 schematic but different. I know that a real JMP and JCM are pretty much the same amp but the 1 watter's sound different. Thanks.

I've posted it here for you, https://ampgarage.com/forum/viewtopic.php?f=9&t=34639. Thought it would be easier to find for people in a new thread.

hello everyone I built this beauty a week ago I wanted to thank Mattec and all the members of the forum who helped to make the diagram. I have a question when I use the amp with a fuzz sound and horrible almost no sustain and I feel that part of the sound is lost. Is this normal? I use the hammond 125a with 8ohms pin 1 and 4 and 16ohms pin 1 and 5 could someone help me understand please? and i add a master volume
