Marshall JCM2000. Will a TSL board work in a DSL.

[Redline]

Seems like a stupid question but it is the same board. Just some extra components on the TSL board obviously. Would I need to mod it for it to work? It has the same connections as the DSL.

[Redline]

Wow. Nobody. Guess I'll just give it a go.

[The Dude]

Well, firstly, it's only been a day. Have a little patience. Secondly, you didn't say which board.

[Redline]

Not trying to be impatient. Usually Enzo would be all over this.

[Justin Thomas]

True, but there are many others just as willing and knowledgable who would be all over it, if given the relevant information.
Dude asked a fair question - what's in it now, what are you trying to put in? Model #s, board #s, schemos, etc. needed, or at least heavily desired. This ain't exactly a tube swap!
And it IS Thanksgiving... traffic might be a little slower than usual. You'll get an answer. If not within two weeks, try again.

the power tube boards are certainly very similar, I have a pile of about 15 of them, all with the heat-related bias leak issue, out of DSLs and TSLs and I can't see the difference enough to identify them, though there are different versions. The preamp boards are of course much more different between the DSL and TSL.

While I haven't had the occasion to swap out the main power amp PCB assy of DSL series with that from a TSL, after downloading the TSL100-TSL122 schematics, I do see there being a lot of differences between the first two tubes, with the additional VacTec cells used. I'd stare at the two boards closely before putting the effort to extract the DSL board first, as well as the schematics. I downloaded the JCM2000_100_dsl100.pdf and the JCM2000_tsl100_100.pdf files from this website to look for the differences:

Guitar Amplifier Schematics and more

Looking at the TSL 60W, which was what I had in my files, it looks like a different animal with regards to interfacing with the front and rear panel boards.

A recent purchase from Marshall was a batch of TSL and DSL boards and lots of differences between the two. So I ask myself, as these amps are obsolete, why would Marshall not rationalize the board production and just make a single PCB that fits either? Sometimes DSL boards are out of stock when they have TSL versions. I've never been recommended by them to use the 'other' type, and they're pretty good for stuff like that. Maybe there's a message there.

Pin compatability is one thing, but performance in a working amp is something that needs to be established and you could do with finding someone who's proven this in practice. Maybe there's a reason for "Just some extra components".
