Mesa Boogie Roadster Repair

Having had a dual rectifier, I can relate to the challenge for an amp tech to troubleshoot and resolve issues as these are very complicated amps.

Although the video is long at roughly 45 minutes, I found it, well, really engaging, almost like a mystery novel. The Guitologist is quite the tech.

So much circuitry in this guitar amp.

    What an awesome video to discover, Richard. I watched the entire thing, fascinated. Fortunately my MB Mark III Simul-Class combo amp continues to perform flawlessly today as it did when I bought it in and about 1982/3.

    No internet, no stores at that time selling these amps – bought directly from MB in Petaluma CA, with drafts and money orders sent by Canada Post to pay for it.

    Thanks for posting this.

        Thanks for the link – and no, I didn’t know about this site. Hope you don’t mind my trolling you there as well? All in the interest of a good (as usual) read.
