Is there a schematic for the JVM HJS somewhere?

I have a PDF copy on my computer. I am not sure it can be posted if an amp is currently in production. If a mod could chime in on this I would be happy to send a copy for them to post in the schematic section. If nobody has one already. I am kind of a novice to complicated drawings but it seems to be well done and easy to read and decipher. It is laid out like the JMD drawing. Very straight forward and not all tight and jumbled up like some I have seen.

It is posted now. Here is a link. I am not sure if this is the most current REV but this is what I have. If I did something wrong please feel free to correct or remove and have me fix it. I have never done this before.

Why is the schematics so much a secret nowdays. Before you could just ask for them. When i visited the Marshall factory in the summer of 1993 i asked for and got a copy of the schematics for the SL-X amp. It was new then and not even availeble to buy in Sweden yet then.

Hi Matt. Santiago personally contacted me and a asked that schematics for current production amps not be made public. They are copyrighted.

Marshall provides them to authorized service shops only. We can post schematics for amps no longer in production.

Hi Surf! No i know it's like that. But still they get out anyway. And people with knowledge can just open up the amps and look.

From what I have read on other forums Santiago has been very forthcoming and generous with his time and explaining his baby the JVMHJS. As much as I would like to have his expertise and experience on this forum. There is no use rehashing any discussion on here about the schematic that has already been discussed. I respect the Mods decision to keep the print from being posted. I found the schematics posted online. Remember, search engines are your friends. Unless of course, he pulled those down. Happy searching. BTW, it's good to hear from you Surf. Here's to you having safe travel home.
