• Guys, we've spent considerable money converting the Les Paul Forum to this new XenForo platform, and we have ongoing monthly operating expenses. THE "DONATIONS" TAB IS NOW WORKING, AND WE WOULD APPRECIATE ANY DONATIONS YOU CAN MAKE TO KEEP THE LES PAUL FORUM GOING! Thank you!

What came stock in

a '93 BB (JTM-50)? There are Sovteks in there now.

EDIT: Marshall USA just told me it's a JTM45 not 50.

Wake it up with at least one vintage Mullard 12AX7/ECC83 in the V1 position. You can pick one up for about $25 or so and that will sweeten up that amp. From there the sky is the limit, literally. The true compliment of tubes in an original JTM45, or a RI that has been modded to get to the original sound, is GEC KT66 power tubes, Mullard GZ34 rectifier tube, and Mullard 12AX7 preamp tubes. That is a $600 to $650 retube at todays prices, mostly for the GEC's if you can find them. But without good replacement output and power transformers, and a nice tagboard to replace the existing PCB board in your amp, all those expensive tubes are wasted. Just my opinion though. But the JTM45 is what I consider the most usable and also pedal friendly Marshall amp out there. That is what I use for my avatar and my #1 and have for years.:salude

Adding up a retube, new iron, replacing the circuit board, bench time and the street price of a used reissue, you might as well look into a used boutique or clone.

If you like to work on your own stuff and don't mind spending some money you'll probably never see again (not that it is necessarily a bad thing) then have at it.
