• 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!

Upgraded my Marshall Bluesbreaker reissue...

I wonder if your output transformer is the earlier (RS) style, which had a different primary impedance than the later style (Drake?) and, therefore, a cleaner sound. I have Heyboers in my JTM45 build and it's good and dirty, just not as dirty as a lead-spec JMP.
No telling what that Mojo-Heyboer OT was specc’d after. I do know that amps B+ was like 475 vDC. It was loudish and hardly distorted between 7-10. My early 90s BBRI had an excellent breakup and being only about 28watts I could greatly enjoy just letting it rip in my living room without frying my ears off. The previous owner had it running EL34s and had disconnected the tremolo also.

I believe the O/P tranny I put in yours is a RS replica Brandon. Sergio cloned a particular RS output with one he had.
