New Amp Build: BYOC Brit 45 with JTM50 modification

[kentuckytukker]

Hi duvoodooman,

Where did you dig up the info concerning the differences between the JTM45 and the JTM50? I've build a JTM45 clone using the BYOC schematic which I like best compaired to the diagram which was accompanied with the kit. Concerning the JTM50 schematic it is very hard to find any info on the web. It also seems that there are many different versions made by Marshall at that time. I've been asked by the owner of the JTM45 clone to modify it to a JTM50 but like to go shure what is realy req'd. Why did you relocate the 2 1M resistors at the input circuit and why did you add the 100nF cap's?

DVM doesn't check in as much as he used to, but hopefully he'll see your post an give you an answer. Knowing him I'm sure there was a good reason for doing what he did!
