[Harp-L] Re: 5F6A Bassman mods for harmonica from Mark and Jim



Hey guys

New to this forum. I've just stumbled upon the Bassman Mods PDF and it looks very useful. I'm using a Blues Blaster with MC-151 element with a 5Meg volume pot. I see lots of stuff on the forums about the crystal elements needing a 5Meg resistance in the amp - is that the purpose/effect of changing the R3/R6 grid load resistors to 5.6 or 8.2 Meg? I've also seen the Jayphat threads so will probably build one if that's needed as well.

Thanks
Tom
