    I have a 1989 JTM45 reissue that has Groove Tube EL34's and a solid state rectifier. Bought this amp in a pawn shop so no info is available. Looking on the web I found that they come stock with 5881's and a tube rectifier...

    I've had no issues with this amp and it is the best sounding tube amp I've ever played (I've had Carvin and Peavey tube amps for the last 20 years)

    Just wandering if anyone has a JTM45 RI with EL34's and a solid state (plug in) rectifier and did you have to do any mods to accommodate the EL34's.

    After playing this amp for the last week, I've falling in love with it and want to try to find more info on it and if it has had mod's done to it.

    Any input would be greatly appreciated

    Thanks

    well 5881 and EL34's have been known to be mixed before e.g. 6100 series some have 34's others had 5881's. My advice is, if you like the tone then who cares? The chances are it was just a factory thing marshall did. Marshall had a tendancy to change tube types when stocks got low (800 series some had 6550's others had EL34's) At the end of the day. Yes it could have been modded, but if you like it so much then it was modded for the greater good.

    My advice.
    If it ain;t broke, don't fix it!

    The JTM45's originally had KT66's. But in the late 80's they started running out of 34's and they decided to re-design it as a 5881 amp. In the mid 90's they started making them with el34's and later they went back to 5881's. I have a 5881 model, but I'm running KT66's in it now, and it's amazing!

    historically, the first marshall jtm45 amps used 5881 tubes. when the 5881 became scarce, the kt66 tubes were used.
